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 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.

Jaime Guerrero


Graduate student

Jaime is a graduate student in the Molecular Biophysics program, with emphasis in the Computational and Systems Biology track. He received his bachelor's degree in Biochemistry/Chemistry from UC San Diego.

In the Jaqaman lab, Jaime is pursuing quantitative microscopy studies of cell surface receptor interactions.

Tra Ngo

Tra Ngo

Graduate student

Tra is a graduate student in the Genetics, Development and Disease program, with emphasis in the Mechanisms of Disease and Computational and Systems Biology tracks. She received her bachelor's degree in Molecular Biology and Mathematics from UT Dallas.

In the Jaqaman lab, Tra employs computational and experimental approaches to study the regulation of endothelial cell surface receptor behavior and angiogenic signaling by the cytoskeleton.

Jesus Vega-Lugo

Jesus Vega-Lugo

Graduate student

Jesus is a graduate student in the Molecular Biophysics program, with emphasis in the Computational and Systems Biology track. He received his bachelor's degree in Mathematics from Universidad del Sagrado Corazon, Puerto Rico, while doing research at the University of Puerto Rico Medical Sciences Campus, where he investigated the molecular mechanisms of mitochondrial dysfunction in heart disease.

In the Jaqaman lab, he is interested in developing computational analysis approaches to quantitatively assess the interactions of membrane receptors with each other, with scaffolding proteins, and with 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.

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.
