BioMy research group studies complex molecular systems by using ultrafast multi-dimensional infrared and non-linear UV/Vis methods. A basic theme is to understand the role of mesoscopic structure on the properties of molecular systems. Many systems have structure on length scales large compare to molecules but small compared to macroscopic dimensions. The mesoscopic structures occur on distance scales of a few nanometers to a few tens of nanometers. The properties of systems, such as water in nanoscopic environments, room temperature ionic liquids, functionalized surfaces, liquid crystals, metal organic frameworks, water and other liquids in nanoporous silica, polyelectrolyte fuel cell membranes, vesicles, and micelles depend on molecular level dynamics and intermolecular interactions. Our ultrafast measurements provide direct observables for understanding the relationships among dynamics, structure, and intermolecular interactions.
Bulk properties are frequently a very poor guide to understanding the molecular level details that determine the nature of a chemical process and its dynamics. Because molecules are small, molecular motions are inherently very fast. Recent advances in methodology developed in our labs make it possible for us to observe important processes as they occur. These measurements act like stop-action photography. To focus on a particular aspect of a time evolving system, we employ sequences of ultrashort pulses of light as the basis for non-linear methods such as ultrafast infrared two dimensional vibrational echoes, optical Kerr effect methods, and ultrafast IR transient absorption experiments.
We are using ultrafast 2D IR vibrational echo spectroscopy and other multi-dimensional IR methods, which we have pioneered, to study dynamics of molecular complexes, water confined on nm lengths scales with a variety of topographies, molecules bound to surfaces, ionic liquids, and materials such as metal organic frameworks and porous silica. We can probe the dynamic structures these systems. The methods are somewhat akin to multidimensional NMR, but they probe molecular structural evolution in real time on the relevant fast time scales, eight to ten orders of magnitude faster than NMR. We are obtaining direct information on how nanoscopic confinement of water changes its properties, a topic of great importance in chemistry, biology, geology, and materials. For the first time, we are observing the motions of molecular bound to surfaces. In biological membranes, we are using the vibrational echo methods to study dynamics and the relationship among dynamics, structure, and function. We are also developing and applying theory to these problems frequently in collaboration with top theoreticians.
We are studying dynamics in complex liquids, in particular room temperature ionic liquids, liquid crystals, supercooled liquids, as well as in influence of small quantities of water on liquid dynamics. Using ultrafast optical heterodyne detected optical Kerr effect methods, we can follow processes from tens of femtoseconds to ten microseconds. Our ability to look over such a wide range of time scales is unprecedented. The change in molecular dynamics when a system undergoes a phase change is of fundamental and practical importance. We are developing detailed theory as the companion to the experiments.
We are studying photo-induced proton transfer in nanoscopic water environments such as polyelectrolyte fuel cell membranes, using ultrafast UV/Vis fluorescence and multidimensional IR measurements to understand the proton transfer and other processes and how they are influenced by nanoscopic confinement. We want to understand the role of the solvent and the systems topology on proton transfer dynamics. -
Zoha Zahid Fazal
Visiting Instructor, Ophthalmology Research/Clinical Trials
BioZoha Zahid Fazal is a postdoctoral research fellow at the Sepah Lab at Stanford Medicine, where her work advances screening innovation and diagnostic automation for retinal degenerative diseases through cutting-edge research and artificial intelligence–driven tools. During her time at Stanford, she has collaborated across the Spencer Center for Vision Research, the Center for Digital Health, the Center for Artificial Intelligence in Medicine and Imaging, the Ocular Imaging Research & Reading Center, and the Mussallem Center for Biodesign—developing a multidisciplinary skill set at the intersection of medicine, applied coding, and computation.
Previously, as a predoctoral scholar, Zoha worked closely with the Director of the Global Health Dermatology Program at Yale School of Medicine, contributing to global training, research, advocacy, and field-based interventions addressing tropical and culturally contextual dermatologic disease. She also gained clinical and research experience through the Northwestern Medicine Adjunct Dermatology Program, supporting patient care, clinical education, and research in skin-of-color dermatology, autoimmune disease, and complex dermatopathies. Through these roles, she helped establish collaborative research initiatives linking U.S. academic centers with her home medical school in Pakistan.
Zoha earned her medical degree from Aga Khan University, graduating with honors in Community Health Sciences, and is recognized for her leadership and impact in community service. As part of AKU’s community education efforts during the COVID-19 pandemic, she co-authored and edited 'How Not to Go Viral', a student handbook, over 1,500 copies of which were distributed to libraries across Pakistan. For her contributions to poverty alleviation and pandemic relief efforts, she was awarded the Quadragon Member of the Year Award in 2020. She has also volunteered extensively in flood-relief operations and rural medical camps across Pakistan, experiences that exposed her to the limitations of resource-constrained health systems and paper-based medical records.
Zoha’s interest in global health research and big-data analytics began early. She graduated with distinction from Cedar College, majoring in biological sciences and advanced mathematics, and spent formative summers working alongside nursing faculty and public health leaders at the institution that later became her medical school. She has since continued to build technical fluency in healthcare data analytics and research software through self-directed coursework. She served as a global research lead from Pakistan for the COVAD Collaborative, led by the NHS Foundation Trust (UK), where her work focused on patient safety, healthcare quality, and vaccine uptake among individuals with autoimmune diseases. As a medical student, she also led Gates Foundation–sponsored interventional studies aimed at improving maternal, neonatal, and child health outcomes in underserved settings.
Looking ahead, Zoha envisions a career as a clinician-scientist specializing in biomedical informatics. Her long-term goal is to design sustainable, scalable, and context-aware digital health systems for developing nations—systems that are grounded in local resources, cultural realities, and environmental constraints. Through human-centered digital health innovation, she aims to advance equitable, evidence-based care globally.
