OBJECTIVE

To obtain postdoctoral research experience in the area of clinical and translational cancer research. More specifically, to become proficient in developing novel clinically relevant therapies for cancer.


EDUCATION

• PhD, Biochemistry, Department of Chemistry, Purdue University December 2006

Dissertation: “Folate receptor-targeted immunotherapy of cancer: Identification of the mechanism of action and augmentation of the therapeutic efficacy through the addition of standard and novel therapies”

Advisor: Philip S. Low, Ralph C. Corley Distinguished Professor of Chemistry


• BS, Physics, Department of Physics, University of Bucharest, Romania June 1997

Major: Biophysics


RESEARCH EXPERIENCE


Purdue University, Graduate Research Assistant August 2000-Present


• Developed and characterized the folate receptor targeted immunotherapy.

• Evaluated the dose-dependent anti-tumor effect of folate receptor targeted immunotherapy

• Identified the immune cell populations (e.g. macrophages, NK cells, CD4+ and CD8+ T-cells) responsible for the elimination of folate receptor positive tumors

• Evaluated in vitro the tumor cell-killing effect of these immune cell populations

• Assessed the tumor infiltrating lymphocytes by immunohistochemical methods

• Designed novel strategies that synergize with folate receptor targeted immunotherapy in eradication of large aggressive tumors.

• Designed and synthesized folate-linked toll-like receptor ligands

• Developed a novel therapy based on folate-linked toll-like receptor ligands that amplifies the therapeutic efficacy of the immunotherapy

• Developed a successful combination therapy involving low-dose radiation and folate receptor targeted immunotherapy that leads to regression and subsequent elimination of large aggressive tumors


EMPLOYMENT EXPERIENCE


N. Simionescu Institute of Cellular Biology and Pathology, Romania, Research assistant, 1997-1999


• Studied the immunoglobulin G trafficking in human placental endothelial cells. In particular, investigated the role of neonatal Fc receptors, expressed on human placental endothelial cells in internalization and transcytosis of immunoglobulin G in order to achieve fetal humoral immunity.
