Visitor of the Week: Dylan Guerin

cshl-visitor-dylan-guerin

Meet Dylan Guerin of the University of Nevada, Las Vegas. The graduate student in Dr. Ai-Sun Tseng’s lab is currently training at his first course at CSHL: Cell & Developmental Biology of Xenopus: Gene Discovery and Disease where he has been perfecting his injection and imaging skills, and learning how others use Xenopus embryo in their work.

What are your research interests? What are you working on?
Our lab is interested in studying the mechanisms underlying regeneration. Specifically, I am interested in genes controlling embryonic eye regeneration in Xenopus laevis.

How did you decide to make this the focus of your research?
I was interested in regeneration before applying to graduate school. It is amazing to me how some animals can completely regrow lost appendages and it would be even more amazing if we could do that as well.

How did your scientific journey begin?
I am just naturally curious about the world and that curiosity was luckily encouraged by my parents. Science was the natural path to follow to feed that curiosity.

Was there something specific about the Cell & Developmental Biology of Xenopus: Gene Discovery & Disease that drew you to apply?
My advisor brought the Xenopus course to my attention as a way to interact with other Xenopus labs as we are the only lab in Nevada working with Xenopus. Personally, I wanted to learn how to perform micro injections and gain more experience with imaging.

What and/or how will you apply what you’ve learned from the course to your work?
The injection and imaging skills I learned here will be useful in my research as they are techniques we use in our lab but I have not had the chance to perfect until now.  From talking to others in the course, I have gained a new perspective about how they utilize the Xenopus embryo from a developmental point of view--where I look at it from a regenerative lens. They are similar but with some interesting differences.

What is your key takeaway from the course?
My key takeaway is that there are many different approaches to using Xenopus to answer scientific questions.

If someone curious in attending this course asked you for feedback or advice on it, what would you tell him/her?
The course is a good way to see what others in your field are doing. Also, you get as much out of the course as you put in.

What do you like most about your time at CSHL?
It was great to meet people from all over the world and get to know them. The personal interactions I have had here have been very enjoyable.

Dylan received a scholarship from the Howard Hughes Medical institute (HHMI) to cover a portion of his course tuition. On behalf of Dylan, thank you to HHMI for supporting and enabling our young scientists to attend a CSHL course where they expand their skills, knowledge, and network.

Meet Chad Hobson of the University of North Carolina at Chapel Hill (UNC-CH). A second-year graduate student in the physics program at UNC-CH and member of Richard Superfine’s lab, Chad is at CSHL training at the Quantitative Imaging: From Acquisition to Analysis course thanks in large part to a fellowship from the Helmsley Charitable Trust and support from the Graduate Student Opportunity Fund at UNC-CH.

What are your research interests? What are you working on?
My main interest is in designing new systems that combine cutting-edge microscopy techniques with force-measurement instruments to investigate the mechanics of single cells. Specifically, I am using a combined light sheet microscope and atomic force microscope to investigate the mechanics of cell nuclei.

How did you decide to make this the focus of your research?
I toured Rich Superfine’s lab during an undergraduate summer program (REU) at Duke University and loved the idea of combining force and imaging techniques and fundamental physics to understand the mechanics of single cells. The field was entirely new to me, but the ability to design and invent as well as use my physics background was inspiring.

How did your scientific journey begin?
During my freshman year of undergraduate school at Lynchburg College, my professor, Dr. John Eric Goff, approached me and asked if I would be interested in conducting sports physics research under his guidance. I started work with him in the summer before my sophomore year and have not looked back. I have changed gears from sports physics to nuclear physics to now biophysics, but my passion for research has remained unchanged.

Was there something specific about the Quantitative Imaging: From Acquisition to Analysis course that drew you to apply?
I really wanted to get hands-on experience with a variety of imaging techniques in order to both broaden my general knowledge of microscopy as well as understand the difficulties and limitations of each technique. These skills will help increase the rigor and success of my graduate research going forward.

What and/or how will you apply what you’ve learned from the course to your work?
Everything I have learned directly applies to our lab. Whether it is general maintenance and care of optics or a more detailed understanding of each component of a microscope, I am excited to share what I have learned with my fellow lab researchers.

What is your key takeaway from the course?
The biggest takeaway so far is that I will never know everything about microscopy, and that is okay. At the course, however, we are building up from the basics so that I can develop a working knowledge that applies to almost all imaging modalities. Moving forward if I need to understand the detailed intricacies of a certain method I have the foundation to do so.

If someone curious in attending this course asked you for feedback or advice on it, what would you tell him/her?
Take it! The instructors are beyond fantastic and helpful, and you will never look at a microscope the same way again.

What do you like most about your time at CSHL?
I have truly enjoyed getting to know the fellow students and instructors at the course. We all come from such different backgrounds and fields, so learning about what brought us all here together has been an enlightening experience. 

Chad received funding support via a fellowship from the Helmsley Charitable Trust and from the Graduate Student Opportunity Fund at UNC-CH. On behalf of Chad, thank you to these organizations for supporting and enabling our young scientists to attend a CSHL course where they expand their skills, knowledge, and network.

Visitor of the Week: Nunya Chotiwan

VOTW (3).png

Meet Nunya Chotiwan of the Umeå University (Sweden) and Molecular Infection Medicine Sweden. The Thai national is a MIMS Excellence by Choice Programme postdoctoral fellow in Dr. Anna Överby’s lab and is at CSHL participating in Blood Brain Barrier. At her inaugural CSHL meeting, Nunya presented a poster titled “Visualizing Invasion and Spread of Neurotropic Tick-borne Flavivirus in Brain by Whole Tissue Ex Vivo Imaging” and though this was “not [her] first time for a poster presentation…it [was her] first time presenting in a neuroscience conference.” The virology-trained scientist “just started working with brains 5 months ago” learned a lot from the meeting and received great feedback and tools to use towards her work.

What are your research interests? What are you working on?
My work focuses on tick-borne flaviviruses. These viruses are in the same family as the West Nile and Zika viruses but are transmitted by tick instead of mosquitoes. These viruses can cause encephalitis (inflammation of the brain), but we do not know how they enter and spread in the brain.  I am interested in using imaging techniques to capture the entry and spread of these viruses in the mouse brain.

How did you decide to make this the focus of your research?
Flavivirus is near and dear to my heart. I have studied it for several years. When I started my postdoc, I wanted to get out of my comfort zone and study this virus from other perspectives. I am always interested in brain and felt like it is very challenging to study. Since several flaviviruses cause encephalitis and there are a lot of unanswered questions in this research area, I picked this topic for my postdoc research. 

How did your scientific journey begin?
I grew up watching a lot of disaster movies, like Deep Impact, Armageddon and Outbreak. In these movies, the real heroes who saved humanity, to me, were the scientists. When I am exposed to science, either in class or in my research, I am always amazed by the complexity of the biology. I always feel excited to design experiments to solve scientific problems. This positive energy is what drives me to continue on this road. 

Was there something specific about the Blood Brain Barrier meeting that drew you to attend?
I am new to this field, I am looking for the conference where I can learn from the experts and get a feedback from my poster. My research interest is about the viral invasion into the brain, which needs to cross some types of brain barrier in order to get to the brain. This meeting is perfect for me.

What is your key takeaway from the meeting?
I always thought blood brain barrier (BBB) is a ‘wall’ that protects the brain, but this meeting gave me an appreciation that BBB is very tightly regulated and dynamic. I am also glad to learn that what I am interested in, choroid plexus, is still understudied. There are a lot of unknown areas that I can study about.

What did you pick up or learn from the meeting that you plan to apply to your work?
My goal for this conference was to find out cell specific markers to identify cell types that are infected with virus and tools to study choroid plexus. Through talks and posters, I have acquired tools, techniques and collaboration that can help me with my project.

If someone curious in attending a future iteration of this meeting asked you for feedback or advice on it, what would you tell him/her?
The quality of science at this meeting is at a high level. Experts in the field did share new findings and even their most recent unpublished data. For those familiar to the filed, you will learn the most current findings, and for those new to the field, you will still learn several exciting information and see where the field is heading.

Blood Brain Barrier is your first meeting at CSHL—what did you think of it?
I imagined that it would be a focused but relaxed meeting with a relatively small number of participants, which enhanced the interaction and networking between the participants. I also imagined that the lab is located in an urbanized area with a lot of buildings. But now that I am here, the meeting is very engaged and there are a lot of networking opportunities. The talks and presentations are very interesting but dense, so my brain is quite overwhelmed with these interesting presentations. The campus, on the other hand, is very beautiful, close to nature and very relaxing. (I am a little jealous of the scientists who work here.)

Thank you to Nunya for being this week's featured visitor. To meet other featured scientists - and discover the wide range of science that takes part in a CSHL meeting or course - go here.

Visitor of the Week: Daniel Lee

cshl-visitor-daniel-lee

Meet Daniel Lee of the California Institute of Technology. The NIH K99 Postdoctoral Research Fellow in David Prober’s laboratory was at CSHL last week to take part in the Workshop on Leadership in Bioscience. This was the first CSHL course for Daniel, who already has plans to return for this year’s Programming for Biology, the Scientific Writing Retreat, and the brand new meeting on Zebrafish Neural Circuits & Behavior.

What are your research interests? What are you working on?
Despite the impact of sleep disorders, the fact that we sleep for a third of our lives, and the evolutionary conservation of sleep-like states, mechanisms that underlie this behavioral state remain poorly understood. My research utilizes animal models to identify novel and evolutionarily conserved sleep regulatory mechanisms.

How did you decide to make this the focus of your research?
Sleep is among the most enduring mysteries in biology. Furthermore, sleep disorders are pervasive in modern societies. Over 10% of Americans suffer from chronic sleep disorders for which therapeutic options are poor, with an estimated annual cost of $100 billion in lost productivity, medical expenses, sick leave, property, and environmental damage.

Progress in understanding human sleep has been hindered in part by the complexity of mammalian brains and the difficulty of using rodent model animals for large-scale behavioral genetic screens. To overcome these limitations, we take a new approach to an old problem, and utilize the amenability of zebrafish to large-scale behavioral and genetic screens in order to provide insights into sleep regulation and function. I and others have recently demonstrated behavioral, anatomical, genetic and pharmacological conservation of sleep in zebrafish and mammals, suggesting that findings we make in zebrafish will likely apply to mammalian sleep. Exploring mechanisms that regulate sleep in the zebrafish animal model can help identify drug targets useful in treating human sleep and associated neurological disorders.

How did your scientific journey begin?
In high school, I attended a public lecture series at a nearby medical school that challenged my youthful beliefs about the current state of medicine. I remember being awed by one particular lecture led by a physician who described huge gaps in our understanding about the causes of various of human diseases. The lecturer quoted the evolutionary biologist Richard Lewontin, “[None of the advances of 20th century medicine] depend on a deep knowledge of cellular processes or on any discoveries of molecular biology. Cancer, for example, is still treated by gross physical and chemical assaults on the offending tissue.” He then implored, “We need more people to become scientist to open that frontier, and to usher the next era of medicine.” The realization that basic research was essential to making mechanistic-based therapies and treatments was a driving force in my choice of a research career in the biomedical sciences.

Was there something specific about the Workshop on Leadership in Bioscience that drew you to apply?
The ability to consistently perform high impact science over one’s career involves more than technical prowess and great experimental design, but also the ability to lead, mentor, and inspire young scientists. My desire in attending this workshop was to develop a greater self-awareness of my approach to leadership, and to acquire a better communication toolbox to mentor and develop teams of scientists.

What and/or how will you apply what you’ve learned from the workshop to your work?
The current state of modern scientific training emphasizes technical and communication skills above all else. The skills to hire, lead, and manage are generally taught secondarily and in an ad hoc manner, if at all. I’ve received excellent scientific training by my mentors, and sought to become a better leader and mentor myself. I will take this toolbox of leadership skills to grow and develop my future lab.

What is your key takeaway from the workshop?
The key takeaway from this workshop is probably best summed up by Alison Antes, one of the co-participants, “Want to get the best research from your team? [The] first law of leadership: be human first, scientist second.” She has written an excellent world view piece on six steps to develop stronger research relationships.

This was your fist course at CSHL. What did you think of it and do you have any plans to attend a future CSHL meeting and/or course?
I plan to! This was an incredible opportunity to learn a large body of information efficiently, and moreover to develop deep bonds with other passionate scientists along the way. Over the next year, I plan to apply for the Programming for Biology Course and the Scientific Writing Retreat, as well the Zebrafish Neural Circuits and Behavior Meeting.

If someone curious in attending this workshop asked you for feedback or advice on it, what would you tell him/her?
Do it! Apply now.

What do you like most about your time at CSHL?
The people. As scientists, we’re not only passionate about expanding our understanding about a poorly understood intellectual area, but we are interested in lifelong learning that helps us to accomplish that. Being thrust together with new people and diverse perspectives at a place like CSHL, you are forced to challenge your heuristics , internally confront gaps in your understanding, and to learn more about yourself in the process. The people make that happen.

Daniel received financial support from the National Institute for General Medical Sciences (NIGMS) to cover a portion of his workshop tuition. On behalf of Daniel thank you to NIGMS for supporting and enabling our young scientists to attend a CSHL course where they expand their skills, knowledge, and network.

Visitor of the Week: Eman Ageely

cshl-visitor-eman-ageely

Meet Eman Ageely of the Southern Illinois University. The PhD candidate in Dr. Keith Gagnon’s lab is with us for her first meeting at CSHL: RNA & Oligonucleotide Therapeutics. Her inaugural CSHL meeting participation was made with a bang, presenting a poster entitled: ‘’Probing the Cpf1-crRNA Interaction with Ribochemical Modification’’. Having presented a poster at two other RNA meetings, this wasn’t Eman’s first time presenting a poster. However, at this meeting, she was able to “interact with people from the field of oligonucleotide therapeutics.”

What are your research interests? What are you working on?
I am studying the structure function relationships of CRISPR-Cas12a and investigating the therapeutic applications of CRISPR.

How did you decide to make this the focus of your research?
During my MSc, I observed an article presentation about CRISPR. I was impressed by this new technology and the potential of such technology in the therapeutics field.

How did your scientific journey begin?
Scientifically, my supervisor Dr. Keith Gagnon has influenced me the most. He always set a high standard for science and gives every opportunity to his student go be the best. Also Dr. Ramesh Gupta has been a big impact on me. Personally, my husband Omar has supported me throughout my study.  

Was there something specific about the RNA & Oligonucleotide Therapeutics meeting that drew you to attend?
It is a great opportunity to present my research and get to interact with knowledgeable people.

What did you pick up or learn from the meeting that you plan to apply to your work?
This is not my first RNA meeting but it is the first meeting I’ve attended with a focus on oligonucleotides. Thus, I learned about a wide range of oligonucleotide therapeutic applications and technology.

If someone curious in attending this meeting asked you for feedback or advice on it, what would you tell him/her?
I strongly recommended it. One of the things that I learned and I believe is important for any scientist who work with oligonucleotide is to look closely for both the chemistry and clinical aspect of oligonucleotide therapeutic.

What do you like most about your time at CSHL?
The networking experience that accompanied the amazing meeting. Our lab collaborates with Dr. Masad Damha and I finally had the chance to speak with him here; and I enjoyed talking with him.
