BIO and Research Narrative
I'm a title
Amar’s scientific interests evolved from fundamental mechanisms underlying cell-fate specification and embryonic patterning (undergraduate @Bennington College) to signal transduction (Gap year research fellowship, Lab of Yosef Yarden, Weizmann Institute) to interrogating neural circuit formation (graduate student in the labs of Alex Kolodkin and David Ginty at Johns Hopkins). Keen to probe how neural circuits relate to behavior in health and disease, Amar did postdoctoral work in Rene Hen’s lab at Columbia investigating the functions of adult-born dentate granule neurons in memory and this continues to be a central focus in the Sahay lab.

Raised in Tennessee, Travis earned his bachelor’s degree in psychology from the University of Tennessee. As an undergrad, he had humble beginnings as a research assistant in the behavioral neuroscience laboratory of Dr. Matthew Cooper. Subsequently, he completed his doctorate in neuroscience in the emotion and memory systems laboratory of Dr. Stephen Maren at Texas A&M University. Travis’ primary scientific interests are in the neurobiological bases of aversively motivated memories, and in the meaningful translation of animal research.
The Interview
Q 1. What excites you about being a scientist?
I am grateful to be able to learn something new every day, all the while helping society by contributing to humanity’s knowledge of the workings of the brain.
Q 2. What inspired you to go into science?
Like many families, my family experienced the hardships of addiction. In turn, I am passionate about alleviating the burdens of mental illness. I see neuroscience research as an important tool in combating these issues.
Q 3. In another life what other vocation would you choose and why?
While I enjoy the lab, I'm an avid guitar player; I'd love to play in a touring rock band.
Q 4. Make one prediction of how science will change health or living in the next 20 years.
What used to be the stuff of science-fiction is increasingly just real science! In the next two decades, I would not be surprised if we see considerable advancements in pharmacotherapeutic interventions for at least some psychiatric illnesses. I believe this will occur in part through the advent and innovative use of neuroscientific tools. Rather than bathe the entire brain in treatment, I believe we will be better able to target problem sites and mechanisms that are at the heart of the disorder. Accordingly, a fundamental understanding of the psychological, biological, and genetic factors that contribute to such illnesses is critical!

The Interview
Q 1. What excites you about being a scientist?
Neuroscientists have developed remarkable tools for understanding brain processes. The notion that mechanisms of mental phenomena is understandable, and that psychiatric disorders can be treated more precisely, is the next frontier in medicine. I am privileged to be able to help in this endeavor.
Q 2. What inspired you to go into science?
I have been interested in the discovery process and the practical applications of my findings since undergrad. As a neuropsychiatrist, there is much more to understand about how the brain creates the mind and how these processes go awry. There is still a lot to learn about how to optimize treatment for neuropsychiatric disorders. I am grateful for medical and technological advancements. I’m looking forward to new and exciting possibilities.
Q 3. In another life what other vocation would you choose and why?
Hard to know exactly. I am already straddling two careers by being a clinician and scientist. I like design and architecture, so perhaps I’d be renovating and “flipping" houses.
Q 4. Make one prediction of how science will change health or living in the next 20 years.
I see the expanded use of circuit-based noninvasive brain stimulation beyond the treatment of mood and anxiety disorders. Over time, we will hone targets and protocols for improved delivery of brain stimulation to treat a broad array of neuropsychiatric disorders.
Liam Evans (Lab tech, BS Psychology Bates College) 2022-2024
Liam is from Sauquoit, New York and attended Bates College where he earned his Bachelor's degree in
Psychology. At Bates, Liam worked in the lab of Dr. Andrew Kennedy where they investigated epigenetic
factors of memory and memory loss. Additionally, Liam competed as a decathlete on the Bates track team.
Q 1. What excites you about being a scientist?
Truthfully, it’s the joy of exploration and discovery that comes along with science. Being able to develop an
idea about something, explore the science behind it, and actually test if your idea is correct. Whether right
or wrong, something is always learned.
Q 2. What inspired you to go into science?
I have always had an interest in the unknown. In 8th grade biology that manifested as wanting to be an
astronaut. As I learned more about the unknown aspects of brain function in college, I have become
increasingly interested in neuroscience.
Q 3. In another life what other vocation would you choose and why?
Perhaps carpentry. I enjoy working with my hands and seeing a finished product come together into
something functional yet beautiful.
Q 4. Make one prediction of how science will change health or living in the next 20 years.
I believe that significant advancements in our understanding and utilization of genetics and epigenetics will
lead the way for more targeted therapeutics of neuropsychiatric illnesses.

Q 1. What excites you about being a scientist?
I love chipping away at unanswered questions to better understand the world we live in.
Q 2. What inspired you to go into science?
Taking a philosophy of mind course in college showed me how much we don’t understand about ourselves and our minds, and I felt inspired to do what I could to gain a deeper understanding of these mysterious questions.
d about ourselves and our minds, and I felt inspired to do what I could to gain a deeper understanding of these mysterious questions.
Q 3. In another life what other vocation would you choose and why?
An architect, because it lets me be creative and positively influence people's way of living and interacting with their environment.
Q 4. Make one prediction of how science will change health or living in the next 20 years.
I think advances in technology will allow scientists to better understand how the brain works as a large distributed network and learn how to target specific parts of the network to improve the outcomes of neurological diseases.
