Research Interests

My general interests are in molecular and cancer biology.

Specific Goal: Understanding how ectopic expression of the transcription factor, TAL-1 (see Fig. 1), contributes to leukemogenesis. Through ill-defined mechanisms, TAL-1 seems to play a significant role in the progression of T-cell acute lymphoblastic leukemia. It is thought that important cellular processes such as cell cycle control, cell signaling and apoptosis (see Fig. 2) are influenced by this mis-expressed protein. Through investigating potential targets of TAL-1, it is hoped that a better picture of how TAL-1 influences apoptotic resistance and cell survival will be realized. In the end, this type of research will hopefully guide the future development of better, more targeted therapies to treat T-ALL at the molecular level.


In our research, we:

  • Assess protein expression in isolated cellular extracts via Western blotting.
  • Characterize intracellular protein expression levels though the use of flow cytometry.
  • Utilize immunofluorescence and confocal microscopy to investigate the localization of various proteins within cells (see Fig. 3).
  • Study the apoptotic response in the malignant Jurkat cell line as measured by caspase activity and TUNEL assays.
