My project is focused on determining whether cytosolic acidification and cathepsin release, following heat shock-induced ELMP, is important for caspase activation and cell death following heat shock.

Daric Wible, Ph.D.
Postdoctoral Fellow

Education:
B.A., Biochemistry & Molecular, Cellular and Developmental Biology, University of Colorado, Boulder, USA
Ph.D., Cell and Molecular Biology, The University of Texas at Austin, USA

I am researching the molecular mechanisms that regulate autophagy and how autophagy affects prostate tumorigenesis and progression.

Youngeun Choi, Ph.D.
Current Position: Postdoctoral fellow, Dana-Farber Cancer Institute/Harvard Medical School; Advisor: Dipanjan Chowdhury
My project focused primarily on understanding how two related inhibitor of apoptosis proteins, cIAP1 and cIAP2, suppressed apoptosis through their distinct interactions with the effector caspases 3 and 7.

Indra Mahajan, Ph.D.
Current Position: Research Fellow, Division of Pharmacology and Toxicology, College of Pharmacy, UT Austin; Advisor: Casey Wright 
I investigated the molecular players that regulate heat shock-induced apoptosis using cells derived from various knock-out mice, as well as cancer cell lines.

Madhavi Malladi, Ph.D.
Current Position: Clinical Research Coordinator at New York Hospital - Queens
My research was primarily focused on understanding the mechanisms by which inhibitor of apoptosis (IAP) proteins and their antagonists regulate caspase activation using Drosophila a model system.

Srinivas Malladi, Ph.D.
Current Position: Postdoctoral fellow with Joan Massague at Memorial Sloan-Kettering Cancer Center
My project was focused on understanding the mechanisms of caspase 9 processing and activation within the apoptosome.

Jaekyoung Son, Ph.D.
Current Position: Tenure-Track Assistant Professor at the University of Ulsan College of Medicine, South Korea
I investigated the intracellular mechanisms responsible for TRAIL resistance in human prostate cancer cells, with a particular focus on the role of p38 MAPKs in this process.

Shankar Varadarajan, Ph.D.
Current Position: Tenure-Track Research Fellow in the Institute of Translational Medicine at The University of Liverpool, UK
I worked on two different research projects; one project dealt with the role of p38 MAPKs in regulating autophagy and lysosomal biogenesis, while the other project involved TNFR1 signaling and receptor trafficking mechanisms.

Chu-Chiao (Crystal) Wu, Ph.D.
Current Position: Postdoctoral Fellow with Robert Krug at the University of Texas Austin
My project was focused on the stoichiometry and dimerization/conformational status of caspase-9 within the Apaf-1 apoptosome complex and its activation mechanism in vivo using a novel caspase-9 knock-in mouse model.

Ting-Chun Yeh, Ph.D.
Current Position: Medical Writer, AROG Pharmaceuticals, Dallas, TX
I worked on understanding how Grim, an endogenous inhibitor of apoptosis (IAP) antagonist in Drosophila, induces IBM-independent apoptosis.

Sunhee Lee, Ph.D.
Current Position: Research Fellow at Samsung Economic Research Institute, Korea
My research project was to elucidate regulatory mechanisms of caspases by IAPs and IAP antagonists during cell death in Drosophila.
