OBJECTIVE: Obtaining a Scientist position.

EDUCATION:

Ph.D. Biochemistry, University of Calcutta, Calcutta, West Bengal, India. 2001.

Thesis title: “Studies on the ribosomal RNA of intestinal parasite Giardia lamblia”

M.Sc. Biochemistry, University of Calcutta, Calcutta, West Bengal, India. 1993.

B.Sc. Chemistry, University of Calcutta, Calcutta, West Bengal, India. 1991.

AWARDS AND FELLOWSHIP:

CSIR/UGC Fellowship, India. 1995- 2000.

ADDITIONAL INFORMATION: Permanent resident (green card holder) of United States.

EXPERIENCE:

Albert Einstein College of Medicine, New York, USA (Dept. of Cell Biology).

Associate (July 2011-Present)

Initiated and overseen project to identify new substrates of CDK6 in murine erythroleukemia cell lysates. This required managing the collaborations with Dr. K. Shokat (HHMI Prof. at UCSF School of Medicine) and Dr. R. Fisher (Prof. at Mount Sinai School of Medicine).

Generated transgenic mouse over-expressing CDK6 in the erythroid lineage. Maintained the breeding colonies and did the genotyping.

Responsible for overseeing the many additional mutant mouse colonies for the lab including breeding, genotyping and determining number of mice for each colony.

Over-expressed kinase active, inactive and analogue sensitive forms of CDK6 (AS-CDK6) in both MEL (murine erythroleukemia) and erythroid progenitor cells and demonstrated that CDK6 is an oncogene in red blood cells and kinase activity of CDK6 is required for blocking differentiation.

Co-expressed and purified active CDK6/Cyclin D3 and AS-CDK6/Cyclin D3 complex using baculo virus system and identified new and novel substrates of CDK6 by chemical genetics.

Collaborated with several postdoctoral researchers to ensure successful and timely completion of projects.

Research Associate (August 2005 – June 2011)

Initiated and oversaw projects to understand how CDK6 (a cell cycle regulator) and PU.1 (an important hematopoietic transcription factor) co-ordinates to block differentiation of murine erythroleukemia cells. This required managing the collaborations with Dr. M. Socolovsky (Assoc. Prof. at UMass. Medical School) and Dr. M. Brand (Senior Scientist, Ottawa Hospital Research Institute, Canada)

Demonstrated that CDK6 phosphorylates and stabilizes PU.1.

Identified several new interactors of transcription factor PU.1 by co-immuno-precipitation and mass spectrometry and confirmed the interactions in-vitro.

Demonstrated PU.1-dependent DNA methylation change in fetal liver erythroid progenitor cells.

Initiated projects to understand how PU.1 gene expression is regulated in erythroid cells.

University of California, San Diego, USA (Dept. of Chemistry and Biochemistry).

Postdoctoral Research Fellow (August 2000 - July 2005)

Initiated projects to identify functional groups within 16S rRNA important for ribosome assembly and EF-G dependent tRNA translocation.

Identified non-bridging phosphate oxygens within 16S rRNA that are important for 30S ribosome assembly, association with the 50S ribosomal subunit and tRNA translocation using phosphorothioate modification -interference analysis.

Identified bases in 16S rRNA important for tRNA translocation using a novel modification-interference assay.

Advised two junior postdoctoral researchers and supervised two undergraduate researchers.

Published research in peer-reviewed scholarly journal article.

Presented research at symposiums with more than four hundred attendees.

University of Calcutta, Calcutta, West Bengal, India (Dept. of Biochemistry).

Graduate student (March 1995-july 2000)

Utilized the intergenic spacer region of 16S rRNA gene of protozoan parasite Giardia lamblia to

develop a PCR-based diagnostic tool for giardiasis.

Developed an in vitro assay system for studying Giardia rRNA processing.

Expressed and purified a nuclear protein fibrillarin of Giardia lamblia in E.Coli.

Managed and mentored several undergraduate researchers.

Published research in several peer-reviewed scholarly journal articles.

Served as teaching assistant in Biochemistry lab courses.
