Shanshuang Chen email
Shanshuang received a BA degree from Zhejiang University, China. In 2008, he started his graduate studies under the supervision of Dr. Jue Chen in Purdue University, Indiana, with a research focus on structural and functional investigation of carbon catabolite repression, in particular the inhibition of E. coli maltose transporter by a central regulatory protein known as EIIAGlc. After receiving his PhD in 2013, he continued as a postdoc for one year in the same lab. In 2014, he relocated with the Chen lab to the Rockefeller University, New York, and left shortly afterwards to join the Gouaux Lab. His current research aims to understand the working mechanisms of ionotropic neurotransmitter receptors using a combination of structural and functional approaches.
Sandipan Chowdhury email
Sandipan graduated from the Indian Institute of Technology (IIT), Kharagpur, India in 2008 with bachelors and masters degrees in Biotechnology and Biochemical Engineering. In 2014 he received his PhD in Biophysics from the University of Wisconsin–Madison. In his doctoral research he used a combination of theoretical, computational and electrophysiological approaches to study the thermodynamics of voltage dependent gating of ion channels. In addition, through the de novo design of a temperature modulated ion channel, his research postulated a molecular framework to understand gating mechanisms of naturally occurring temperature gated channels. Sandipan joined the Gouaux laboratory in the summer of 2014 to study structural mechanisms of ligand dependent gating of neurotransmitter receptors.

She was granted a PhD in Biochemistry in 2002 from the University of Oregon. Her postdoctoral training was carried out at the Vollum Institute where she studied anchored PKA signal transduction. Since joining the Gouaux lab in 2008, she has spent her time studying the molecular mechanisms of neurotransmitter transporters and receptors.
Chia-Hsueh Lee email
Chia-Hsueh earned his BS and MS from National Taiwan University. While an undergraduate, he studied the role of Na+/Ca2+ exchanger in intracellular Ca2+ dynamics. He then focused on the effect of permeant ions on Mg2+ block of NMDA receptors. In 2010, Chia-Hsueh joined the Gouaux lab as a PhD student.
Wei Lü email
After receiving his Diploma in biology from the University of Göttingen, Germany, Wei pursued his PhD studies at the University of Freiburg, in Professor Oliver Einsle's laboratory, where he studied the structures and gating mechanism of the formate channel FocA and nitrite channel NirC by X-ray crystallography and planar lipid bilayer electrophysiology. He joined the Gouaux lab in 2012 and his current research focuses on the structural and functional characterization of ligand-gated ion channels.
Steven Mansoor email
Steve graduated from Reed College in 1997 with a BA in Biochemistry and Molecular Biology before matriculating into the MD/PhD program at Oregon Health & Science University in 1999. For his PhD dissertation, he developed fluorescence techniques to study membrane protein structure and conformational changes, with a focus on understanding the dynamics of G-protein coupled receptor activation. Currently, Steve is a clinical fellow in the Department of Cardiovascular Medicine at OHSU and has joined the Gouaux lab to investigate the structure/function of purinergic receptors.
Jennifer Michel email
Senior Research Associate
BS, Denison University, 1995
PhD, University of North Carolina at Chapel Hill, 2000
It was in the Chemistry Department of Denison University in Granville, OH, that Jennifer Michel found herself in her first research endeavor of synthesizing buckminsterfullerenes, or buckyballs. Taken with research but not completely convinced that chemistry was her calling, she completed her undergraduate degree in Biology. She spent her graduate training in sunny Chapel Hill where she focused on eukaryotic cell cycle regulation by ubiquitin-mediated proteolysis using mammalian and yeast model systems. Her postdoctoral training was carried out at the Vollum Institute where she studied anchored PKA signal transduction using a mouse model system. A happy and content resident of the Pacific Northwest, she now researches the molecular mechanisms of neurotransmitter receptor function in the Gouaux lab.
Aravind Penmatsa email
Aravind received a Bachelor’s degree in Pharmaceutical Sciences from Osmania University, India in 2003. He joined the Centre for Cellular and Molecular Biology (CCMB), Hyderabad, India for a PhD program in Biophysics and Structural Biology, as a joint student in the labs of Dr. Yogendra Sharma and Dr. Rajan Sankaranarayanan. His thesis work during the years 2004–2009 dealt with the ion-binding properties and structures of βγ-crystallins and neuronal calcium sensors. His work with multiple crystal structures of calcium-bound βγ-crystallins corroborated the presence of a universal motif for calcium-binding in this superfamily of proteins. He joined Eric Gouaux’s lab in early 2010 and will be working towards understanding the structure and pharmacology of biogenic amine transporters.
Kathryn Sackinger email
Kathryn has lived in Portland her entire life, attending high school at Metropolitan Learning Center and going on to earn a BA in Chemistry at Reed College in 2013. Her undergraduate thesis united her established foci of organic synthesis and atmospheric chemistry, but fell short of incorporating her developing interests in neuroscience and pharmacology. After spending a year taking classes in biology at PSU, she joined the Gouaux lab to study the structure and binding of neurotransmitter transporters.
