Current Lab Members

Marion B. Sewer

Principal Investigator

Dr. Sewer earned a Ph.D. in Pharmacology from Emory University School of Medicine. At Emory she studied the regulation of hepatic and renal cytochrome P450 expression and activity in models of inflammation under the mentorship of Dr. Edward T. Morgan. She carried out postdoctoral training in the laboratory of Dr. Michael R. Waterman in the Department of Biochemistry at Vanderbilt University on the transcriptional regulation of steroid hydroxylase P450 expression.

Ranita Ghosh Dastidar

Ranita is a postdoctoral scientist who joined the lab in February 2014. She earned her masters and doctoral degrees from the University of Texas at Dallas in the field of Molecular and Cell Biology, where she investigated the effects of hypoxia on protein localization yeast. Ranita’s work in this laboratory involves investigating the mechanisms that regulate communication between the endoplasmic reticulum and mitochondria. She also enjoys teaching and being involved in outreach programs for high school and undergraduate students.

Scott Robinson

Scott M. Robinson is a postdoctoral scientist, who joined our lab in December, 2013. Scott eaned his PhD in the joint doctoral program at UCSD-SDSU, in Dr. Feurer's lab. In his doctoral studies, he investigated the role of the coxsackievirus B3 in multiple sclerosis and Alzheimer's, using mouse models. He received his master's degree from the University of Chicago investigating the chemistry of the Azoarcus ribozyme. Scott is investigating the role of oxysterol binding protein-related proteins (ORPs) role in the transit of cholesterol and sterol intermediates in steroid hormone synthesis. When he is not in the lab, Scott enjoys following/watching the Anaheim Ducks, San Diego Padres and San Diego Chargers teams.

Tamara Escajadillo

Tamara is a talented undergraduate student at Cal State Dominguez Hills. She is carrying out studies on the role of oxysterol related-binding proteins (ORPs) in glucocorticoid production. Her studies have linked this family of lipid binding proteins to regulating inter-organelle substrate exchange during cortisol biosynthesis and to modulating de novo cholesterol metabolism.  She is also examining the role of A-kinase anchoring protein 13 in cAMP signaling and adrenocortical steroidogenesis. Tamara also is known in the lab as the cake pop aficionado, but is known for her oatmeal cookies and coconut macaroons.

Hongxia Wang

Hongxia is a Staff Research Associate who provides technical support to all members of the lab. She also is carrying out studies aimed at defining the role of examining the role of post-translational modification in regulating the function of several proteins, including steroidogenic factor-1, NONO, and diacylglycerol kinase.

Jia Yang

Jia is a postdoctoral scientist from Shenyang, China who joined the lab in May 2012.  She obtained her Ph.D. from Shenyang Pharmaceutical University in Shenyang, China. Her project entails characterizing the mechanism by which NONO (p54nrb) regulates steroidogenic gene transcription in the human adrenal cortex.

 

 

Angelica Gonzalez-Sanchez

Angelica is a junior majoring in Chemistry from the University of Puerto Rico at Cayey. She is a summer research scholar and a part of the STARS and Endocrine Society's Minority Access Programs. Her project entails examining the effect of stress on steroid hormone biosynthesis in adrenocortical cells. She enjoys reading, watching television and movies, and shopping.

Christina Robinson

Christina is a summer research student in the SURF program. She is a rising sophomore at Northwestern University where she is majoring in Biochemistry. She is investigating the role of nutrient availability in regulating steroid hormone production and adrenocortical gene expression.
