Khuloud Jaqaman, Ph.D.

Khuloud Jaqaman, Ph.D.

Principal Investigator

Khuloud joined the Department of Biophysics at UT Southwestern Medical Center in January 2013 and is excited about pursuing her research program and contributing to the education and training of students and postdocs.

Khuloud received her Ph.D. from Indiana University Bloomington, where she did research in molecular dynamics and protein folding. She then did her postdoctoral studies with Gaudenz Danuser at the Scripps Research Institute, where she got immersed in the fascinating world of investigating receptor dynamics and function in living cells.

Before coming to UTSW, she was an Instructor in the Department of Systems Biology at Harvard Medical School. 

Bruno da Rocha Azevedo, Ph.D.

Bruno da Rocha Azevedo, Ph.D.

Lab director

Bruno is interested in how cells interact with the extracellular environment, and now in the Jaqaman lab he wants to take his studies to the single-molecule scale. For his Ph.D., Bruno studied the interaction between pathogens and the mammalian host. During his postdoctoral trainings at Virginia Commonwealth University and UT Southwestern, and as a Young Talent Research Fellow at Federal University of Rio de Janeiro, he then studied the interaction between mammalian cells and 3D extracellular matrices.

Bruno is the director of the experimental branch of the lab, mentoring and collaborating with students and fellows in order to obtain amazing data! His research project is focused on the link between the dynamics, interactions and signaling of VEGFR2 on the endothelial cell surface.

Anthony Vega

Anthony Vega

Graduate student

Tony is a graduate student in the Molecular Biophysics program. He received his bachelor's degree in Biophysics from St. Mary's University, San Antonio, Texas.

Tony is interested in computational image analysis and is developing tools for the quantitative analysis of molecular dynamics and interactions from multi-channel light microscopy data. He is primarily studying membrane microcluster - actin cortex interactions in a collaboration with the Rosen lab at UTSW.

Xian Cheng, Ph.D.

Xian Cheng, Ph.D.

Postdoctoral fellow

Xian received her PhD in Biophysics from the University of Wisconsin-Madison, where she worked in Prof. Tom Record's lab on thermodynamic methods to study individual atom-atom preferential interactions of amides, salts and nucleic acids in water, which can be used to predict/interpret atom-atom contacts in protein assembly, and protein-ligand and protein-nucleic acid complexes among other things.

In the Jaqaman lab, she is interested in learning quantitative microscopy techniques to study the interactions between receptors and downstream effectors.

Aparajita Dasgupta, Ph.D.

Aparajita Dasgupta, Ph.D.

Postdoctoral fellow

Aparajita received her PhD in Biotechnology from the National Centre for Cell Science (affiliated with Pune university, S.P.P.U), India, where she studied the effect of a novel triterpenoid AECHL-1 on tumor angiogenesis and metastasis. She learned that AECHL-1 could inhibit neo-vessel formation and stall metastasis and EMT by perturbing the cell’s cytoskeleton. Thus, her interest was piqued by the influence that cytoskeletal dynamics can wield on cellular morphology, behavior and survival.

In the Jaqaman lab, she is engaged in studying the regulation of cell surface receptor mobility and signaling by the underlying actin cytoskeleton, using several high resolution and quantitative imaging techniques.

Luciana De Oliveira, Ph.D.

Luciana De Oliveira, Ph.D.

Postdoctoral fellow

Luciana received her B.Sc. and master’s degrees in physics from the University of Santa Maria and a PhD in physics from the University of Bologna. In Santa Maria she worked with numerical modeling of superhydrophobic systems and the construction of phylogenetic trees using random walks and fractal geometry. During her PhD and a previous post-doctoral experience she worked on the stochastic description of biological systems with the master equation and nonequilibrium thermodynamics.

In the Jaqaman Lab, Luciana is developing a stochastic mathematical modeling framework to derive inter-receptor interaction kinetics from the subset of interaction events observed by live-cell single-molecule imaging.

Tieqiao (Tim) Zhang, Ph.D.

Tieqiao (Tim) Zhang, Ph.D.

Microscope manager

Tim received his Ph. D in physics from Peking University, Beijing. China. He has worked in the fields of ultra-fast time resolved laser spectroscopy, optical microscopy and imaging. In the past decade, he focused his research on super-resolution optical microscopy and novel technologies for live cellular imaging.

Tim divides his time between the Jaqaman, Rosen, Yu and Rice labs. In the Jaqaman Lab, he keeps our microscope in best shape and collaborates with other lab members to utilize optical microscopy to study single molecule events. 

Mark Kittisopikul, Ph.D.

Mark Kittisopikul, Ph.D.

Visiting postdoctoral fellow

Mark received his B.S. in Biological Chemistry and Mathematics from the University of Chicago working in the labs of Professors Ka Yee C. Lee and Aaron Dinner where he was initially introduced to the intricacies of the cell membrane. He earned his Ph.D. from UT Southwestern in the lab of Gurol Suel from the Molecular Biophysics program with an emphasis in Computational and Systems Biology. There he studied the dynamics of bacteria as single cells, in host-pathogen interactions, and in biofilm communities through image analysis and simulation.

Mark is currently in the Goldman lab at Northwestern University, studying the relationship between the function and distribution of nuclear lamins using quantitative structured illumination microscopy. He works closely with the Jaqaman lab on the development of novel algorithms to filter and segment intersecting curvilinear structures in microscopy images.
