Liu
Yang Liu, Ph.D.

Yang Liu received her PhD degree in Electrical Engineering at Zhejiang University, China in 2009. She obtained her postdoctoral training at the University of Minnesota before transferring to the Biomedical Engineering Department at the University of Houston. Her research interests include noninvasive  bioelectrical impedance tomography, muscle activity imaging, forward and inverse problem numerical calculation, computer modeling and simulation.

Rasaputra
Komal Rasaputra, Ph.D.

Background: Dr. Rasaputra joined Dr. May’s lab at University of Houston in 2013. She received her PhD degree in Cell and Molecular Biology from the University of Arkansas and United States Department of Agriculture-Agricultural Research Services (USDA-ARS) in 2010. She has a MS degree in Biotechnology and BS in Biochemistry from Madras University, India. Her previous work as a research fellow in New York at Albert Einstein College of Medicine focused on studying the proteins associated with Type-IV secretion system, involved in bacterial pathogenicity.

Research Interests: Dr. Rasaputra’s research interests include understanding the role of various proteins in regulating molecular mechanisms involved in pathogenic diseases in order to overcome disease associated challenges and design therapeutics for treatment. Her current research focus is to understand the molecular dynamics, immune response and virulence mechanisms involved in host-pathogen interactions during infection and profiling biochemical host-pathogen interaction pathways.

Sen
Anando Sen, Ph.D.

Graduate school: Deprtment of Mathematics, University of Houston (graduated May 2012)

My research concerns the application of mathematics to medical imaging. My doctoral project gave me an opportunity to work with image reconstruction techniques for region-of-interest computed tomography (CT). I have been a postdoc at Dr. Howard Gifford's laboratory since August 2012. My current work is the development of human-model observers for image quality assessment in nuclear medicine. Image quality is defined by how well observers can perform a specified task with a set of test images. Observers can be humans or a mathematical algorithm (model). The goal is to develop model observers with high performances which at the same time can match human perceptions. Model observer studies are useful for technology development and can replace human studies which are highly time consuming.

Research interests: Image Quality, Model Observers, Inverse Problems, CT, SPECT, PET, Image Reconstruction, Mathematical Modelling

Computational skills: Linux shell scripting, IDL, Matlab, C/C++, Mathematica, Latex

Sershen
Cheryl Sershen, Ph.D.

Background: Cheryl Sershen joined the May lab as a Post-doctoral Scientist in October 2012. She received her Ph.D. from the University of California at Davis in 2009.  She received an M.S. in mathematics from Stanford University in 2001 and an M.S. in engineering from Columbia University in 1996. In her previous work, she was a postdoctoral researcher at the U.C. Davis Genome Center and bioinformatics researcher at the Baylor College of Medicine.

Research Interests: Dr. Sershen’s research interests include: large-scale simulation in the modeling of biological systems such as kinetic, Monte Carlo, non-equilibrium modeling of stressed-induced duplex destabilization in DNA, development of multi-scale models to portray host-pathogen interactions like those of Mycobacterium tuberculosis and Francisella tularensis, agent based modeling and dynamical systems, and large scale bioinformatics studies of diseases like cancer and autism.

Tao
Zewei Tao, Ph.D.

Zewei received his PhD and MD in 2004 from Zhejiang University School of Medicine, Hangzhou, China. Before he came to the United States of America, he was a cardiologist in Changsha, China. By supplying prescription and performing interventional therapy, he treated and cured patients with cardiovascular system problems such as coronary artery disease, congestive heart failure, hypertension and arrhythmias. At that time his research focused on cardiac remodeling in patients with cardiac dysfunction. After he came to USA, he has been concentrating his career goal on cardiac tissue engineering. He has already engineered a cardiac tissue patch; he hopes these cardiac tissue constructs can help repair myocardial infarction in patients who suffer from a heart attack. He is also interested in fabrication of a bioartificial heart. By seeding neonatal cardiac cells and cardiac stem cells in a heart scaffold, a dead heart may be revived. He hopes, some day in the future, his bioartificial heart can be used as an alternative heart transplant.
