Pushkar Pendse

Ph.D. Chemical Engineering, UMD (2013)
B. Chem. Eng., Institute of Chemical Technology, Mumbai, India
(2007)

Research Topics

Pushkar's research consists of molecular simulations of an important model for secondary active membrane transport proteins, i.e., lactose permease (LacY). He has aided in the development of a new method to predict conformational changes in LacY towards the periplasmic-open state. This method has potential for use with other membrane proteins. His additional interests in LacY are in probing the binding affinity of sugars and proton translocation mechanisms.

B.S. Chemical Engineering, UMD (2012)

Research Topics

Viviana began her research in my lab as an undergraduate and continued research as a M.S. and Ph.D. student. As an undergraduate, she aided in testing a new lipid force field for polyunsaturted fatty acid (PUFA) chains. She then worked on researchering yeast membrane models of the plasma membrane, trans-Golgi Network and endoplasmic reticulum. She also worked on studies of the important lipid transport protein, Osh4, and collaborative work with Dr. Mikhail Anisimov on characterizing solutions with hydrotropes.

B.S. Sharif University of Technology (Chemical Engineering, 2011)

Research Topics

Pouyan did his master's at UC-Irvine and research with Prof. Hung Nguyen. His research initial work at UMD involved studies of secondary active transporters (SATs), such as, lactose permease and Mhp1. He moved on to work on modeling the E. coli cytoplasmic membrane for use in investigating its tolerance to produced chemicals like ethanol. He also simulated condensed phases of PC lipids to study the structure of the ripple and gel phases. Pouyan also collaborated with Dr. Berger (U. Virginia) on Plexin dimerization of the transmembrane and juxtamembrane regions of this large protein.

Placement

Postdoctoral Fellow in Prof. Shukla's Lab at U. Illinois Urbana-Champaign.


Nick Guros

Ph.D. Chemical Engineering, UMD (2019)
B.S. Cornell University (Chemical Engineering)

Research Topics

Modeling of hemolysin, 5HT3, and CDK5 for applications to biosensing. Nick was co-advised by Arvind Balijepalli from NIST. The focus of Nick's reserach is to use all-atom molecular simulations of the hemolysin pore, 5HT3 structure and function and CDK5. He also worked on developing a Field-Effect Transitor (FET) to do expeirmental measurments of chemicals bound to these proteins.

Placement

Scientist at AstraZenca/MedImmune.

B.A. North Georgia College & State University (English with minor in Physics, 2006)

Research Topics

Alison researched the energetics of beryllium ion binding to phosphoserine in lipid bilayers, and the effects of ether linkages on bilayer properties. Dr. Sergei Sukharev (UMD/Biology) co-advised her work on beryllium. She also was co-advised by Dr. Rich Pastor (NIH/NHLBI) working on long-range LJ with PME and ion effects on polymers.

Placement

Structural Biology and Bioinformatics Department, CSIR- Indian Institute of Chemical Biology (CSIR-IICB)
M.S. Birla Institute of Technology, Mesra, India (Bioinformatics, 2008)

Research Topics

Indrani's research first focused on studying sphingomyelin-phospholipid mixed bilayer and how membrane properties are effected by sphingolipids. She has brought to the lab expertise in Gromacs and also tested the use of this software with the CHARMM36 lipid force field. She has also been involved with running MARTINI simulations of Plexin dimerization. She worke on secondary active transporters (uniporters) and predicting structural changes. Her final project involved the study of bio-produced chemicals and their effect on cellular membranes.
