I’ve always been fascinated by the complex interactions between animals and their environment. As a grad student, I studied pheromone signaling in S. cerevisiae and then discovered the wonderful C. elegans system as a postdoc in Cori Bargmann's lab then at UCSF. My lab continues to use C. elegans as the primary experimental organism, although we have also started some work in the vertebrate nervous system and even in Drosophila.  A PI's ‘job’ is constantly unpredictable and always interesting, and it is great fun to be able to interact with and learn from so many smart, interesting, and interested lab members and peers.  I love to travel (the more remote the better), am a bookaholic and a movie buff, and am trying to teach myself to play the drums.

Hillary Katz

Lab Technician

B.A. Smith College


I have worked in the lab for over 25 years. I have held various positions from Research Associate to Lab Manager to Applications Scientist in academia as well as industry. In the Sengupta Lab I am responsible for ongoing daily lab support and preparation of consumables. In my spare time I enjoy reading, baking, and spending time with my family.

Tzu-Yi Lin

Lab Manager

B.A. Skidmore College


I earned my B.A. degree in general Biology in 2019, studying the influence of heavy metal on pathogenicity in E. coli. Before proceeding to the next step, I am here to expand my knowledge and experience with research in a lab setting so that I can be better prepared for my graduate studies. Besides molecular biology, I’m also fascinated by human physiology and virology. Aside from science, I enjoy cooking, traveling, and playing tennis

Postdoctoral Fellows

Nathan Harris

Ph.D. University of California San Francisco

(Advisor: Grae Davis)


I am interested in the mechanisms by which an animal's experience influences neuronal gene expression, and how alteration of gene expression drives neuronal plasticity. I am using C. elegans thermotaxis behavior and temperature preference as a model in which to connect stimulus-dependent changes in gene expression to neuronal function and behavior. In my free time I enjoy rock climbing and listening to music.

I am interested in how primary cilia are organized and maintained to fulfill the diverse roles they play in sensory signal transduction. I am focusing on the mechanisms involved in forming and maintaining the many specialized and diverse forms of sensory cilia observed on C. elegans chemosensory neurons. Presently I am trying to determine how one of these sensory primary cilia achieves a highly branched morphology.

I am interested in understanding the role of the sensory nervous system in adaptation to changing environmental conditions, and the implications of this process on the evolution of developmental and behavioral traits. I am particularly focused on the role of interspecific and intraspecific chemical signals and how these regulate neuronal development and function. C. elegans feeds on diverse bacteria, some of which can colonize its intestine. These different food sources can have profoundly different effects on development and physiology. My work is currently focused on understanding how nutritive cues and secondary metabolites from bacteria are sensed and transduced by the worm to alter nervous system function.

Ph.D. University of Massachusetts Medical School 

(Advisor: Mike Francis)


I am interested in understanding how cilia morphology regulates sensory neuron function. Chemosensory neurons in C. elegans exhibit a range of morphologically distinct cilia. My current project aims to characterize how specialized cilia morphologies contribute to the unique responses of individual chemosensory neurons, and how in turn sensory activity shapes cilia structure. In my free time, I enjoy watching movies and exploring national parks.

I’m interested in the mechanisms  by which genetic factors contribute to  experience-dependent plasticity in thermosensory neuron function. Currently, I am investigating how food deprivation alters thermosensitivity in C. elegans. In my free time, I enjoy taking pictures and watching good movies.

Tyler Hill

Neuroscience Ph.D. Candidate

M.S. Kennesaw State University 


I am interested in understanding how organisms sense their surroundings and translate those sensory signals into relevant behaviors. In particular, I am interested in the mechanisms by which C. elegans adapts its behavioral response to differences in cultivation temperature. In my spare time I love reading speculative fiction, singing, going to concerts, and dancing!

Munzareen Khan

Neuroscience Ph.D. Candidate

B.S. University of Connecticut


 I am interested in learning how neural circuits integrate sensory stimuli and process information to generate relevant behavior and how the processing mechanisms change under different conditions. My current project examines an olfactory plasticity paradigm to understand how experience and context modulates neural activity and behavioral output. In my spare time I love to travel and learn about different cultures, read, and write.

MCB Ph.D. Candidate 

B.S. UMASS Boston


I am interested in exploring how different microbes can affect C. elegans behavior through its diet by providing ascaroside intermediates. Ascarosides are small molecules, produced by the worm, that act as chemical signals used to regulate behavior. My project will explore how Providencia bacteria can induce worms to aggregate by influencing worm ascaroside signalling.

MCB Ph.D. Candidate 

B.S. University of Maryland College Park 


I'm fascinated in organisms with alternative developmental programs & life cycles and how these metabolic and molecular "remodeling" events change animal behavior, pathogenesis, and reproduction. I'm currently investigating how the C.elegans dauer larvae modulates is chemosensory responses and chemotaxis strategies in response to attractive and aversive cues.

Neuroscience Ph.D. Candidate 

M.S. Brandeis University 


I am passionate about molecular neuroscience, and intrigued by the mechanisms regulating the dynamic changes of synapses. The majority of mammalian cortical neurons actively maintain a single primary cilium throughout the life of an animal, however their function is largely unknown. My current work explores a potential role for cilia-mediated signaling in developed mammalian neurons. Outside of the lab, I like to explore the New England coast line, snap photos, and cruise on my bike.

I am a junior at Brandeis, majoring in Neuroscience and minoring in HSSP and Anthropology, investigating with Nathan transcriptional mechanisms that affect AFD and thermotaxis behavior. Outside of the lab, I like to watch Netflix, travel and hang out with friends.

I am currently a junior at Brandeis working with Alison to investigate how chronic and acute disruption of intraflagellar transport affects the localization of sensory signaling proteins in C. elegans. Outside of the lab, I like to read, make scrapbooks, and spend time outside with my friends.
