Christopher J. Potter

Principal Investigator

Chris Potter is an Associate Professor in the Department of Neuroscience at Johns Hopkins University. He is also a member of the IBBS Center for Sensory Biology. He received his B.A. from University of California Berkeley and his Ph.D. from Yale University. His postdoctoral research was carried out at Stanford University with Dr. Liqun Luo.


Chris Potter

Darya Task

Graduate Student

Darya graduated from the Ohio State University in 2011 with a B.S. in Psychology and a B.A. in Spanish. As an undergraduate, she worked in the lab of Dr. Bennet Givens, studying the effects of ethanol on impulsivity, working memory and the theta rhythm. Before coming to Hopkins, she worked for a year as adjunct faculty at Rhodes State College, teaching Anatomy and Physiology labs and First Year Experience. She is currently investigating olfactory signalling in the larvae.



Ali Afify

Postdoctoral Researcher      


Ali got his Bachelor and Master’s degrees in Zoology from Cairo University, where he worked on mosquito ecology. He was awarded the Fulbright Fellowship in 2007 and the Max Planck Fellowship in 2010.  Ali earned his PhD in 2014 from the University of Konstanz. During his PhD, he worked on mosquito olfaction, mainly what odors attract/repel mosquitoes from host finding and oviposition. He is currently interested in how different odorants are coded at the receptors and glomeruli level in Anopheles gambiae.


Sarah Maguire

Postdoctoral Researcher      


Sarah earned her A.B. in Ecology and Evolutionary Biology from Princeton University and her Ph.D. in Neuroscience at the University of Pennsylvania. While at Penn, she studied the genetics of sleep and circadian rhythm in fruit flies with Dr. Amita Sehgal. At Johns Hopkins, Sarah will use novel genetic reagents developed in the Potter lab to study the biological basis of olfaction in fruitflies and mosquitoes


Kateline Robinson

Research Technician      


Katie earned her bachelors degree in Biology from York College PA in 2016. Her interest in bugs led her to perform seasonal work at the Pennsylavia Department of Agriculture in the Entomology Division, where she cataloged and examined many insect species. She is excited to now work in an insect research group!




Elizabeth Marr

Research Technician      


Liz is currently persuing a career as a Medical Technician in the Baltimore area.


Chun-Chieh Lin

Graduate Student (2010-2015) and Postdoc (2015-2016)

Chun-Chieh earned his M.D. from Fu Jen Catholic University in Taiwan before joining the Dept of Neuroscience in 2009.  Chun-Chieh characterized a novel pheromone, developed FgSSR, and developed the HACK method for swapping transgenic components. He is now a Resident in the Department of Pathology and Cell Biology at Columbia University Medical Center.

Sonia Chin

Graduate Student (2011-2016)

Sonia developed a olfactogenetic approach to link neuron acttivities to behaviors. A paper describing her Thesis work regarding olfactory-guided oviposition is in progress. She is now pursuing her interest for teaching biology at Friends School in Pennsylvania.


Deidre St. Peter

Research Technician       10/1/10 to 11/24/11

Deidre is currently a medical student at the University of Maryland School of Medicine. 


Ling Bai

Rotation Student 04/15/10 to 07/15/10

Ling earned a Bachelor of Science degree from the Department of Biological Sciences at Tsinghua University before joining the Dept of Neuroscience in 2010. She is characterizing intersectional expression patterns to manipulate PN activity for behavioral analyses.

Olena Riabinina

Postdoctoral Researcher 05/2012 to 03/2016

Lena received a MSc in Applied physics from the National Technical University of Ukraine in 2006, and a PhD from the University of Sussex in the UK in 2009. She joined the lab in 2012, and developed the second generation of the Q-system (QF2)(Riabinina et al, 2015, Nat Methods). Lena introduced the Q-system into the malaria mosquitoes Anopheles gambiae.
