Research Interests:

The overarching theme of my research is to define and delineate complex dynamic systems -- both biological and synthetic -- in terms of tractable yet accurate mathematical models. My diverse training in engineering and medicine puts me in a strong position to make significant progress toward these goals. I firmly believe that we are at an inflection point in our ability to minutely quantify enough aspects of complex systems and to computationally use vast troves of such data to make increasingly accurate predictions about even systems that are not completely understood. The ongoing advancements in clinical measurements and rapid growth in the availability of computational resources presents a unique opportunity to develop inexpensive tools that circumvent inefficient manufacturing process operations and streamline the diagnosis and treatment of diseases in patients. My current research is working toward such a clinical tool that takes advantage of fine-grained but readily available blood cell measurements, and predicts risk for a set of specific diseases for individual patients. In the short-term, I aim to continue developing data-driven population dynamics models for blood cells to predict onset and risk of several important diseases. Using this approach, I also intend to develop hypotheses for the underlying molecular and cellular mechanisms of disease conditions, which can thereafter be investigated using experiments. I plan to integrate these models for the various lineages of white blood cells in order to investigate the crosstalk in the immune system - a subject with vast potential applications.

From a process systems perspective, I intend to continue developing mathematical models for particulate systems, which can then be utilized for process control and optimization. I have significant experience with developing numerical techniques to solve complex partial differential equations, which I would like to continue incorporating into my research. One of my primary goals is to develop realistic models, which can actually be used for practical applications. With this intent in mind, I plan to continue collaborating closely with experimentalists in order to use systems engineering with a practical application.

Research experience:

I am a Chemical Engineer by training, and have worked on a wide variety of research projects within the field, and in several other realms of basic science and engineering. The common denominator across all my research experiences is mathematical modeling and systems engineering. From working on non-linear system dynamics pertaining to reaction engineering, to developing mechanistic mathematical models for improving processes operation in pharmaceutical drug manufacturing, and now working with clinical data to understand human pathophysiology, I have been interested in different fields where I feel I may be able to make a significant contribution using the core skill sets of systems modeling. While working as a theoretician during my PhD tenure, I collaborated closely with my experimental colleagues in order to develop realistic mathematical models and better understand the underlying assumptions required for the models. Towards the end of my PhD, I was drawn into the enigma of systems biology, which led me to switch fields and broaden the applications of my mathematical modeling skills. In my current position, I am working in an extremely multi-disciplinary environment where I am leveraging my engineering training and expertise to develop models that can improve disease prognosis and alleviate the shortcomings of a delayed therapeutic intervention while also testing hypotheses and revealing details about molecular and cellular disease mechanisms. A specific disease condition -- sickle-cell disease -- has physical and chemical mechanisms with deep relevance to my chemical engineering training, and I am studying the biorheological properties of blood precipitating a clinical sickle cell vaso-occlusive crisis. Our work motivates a collaboration with single-cell assay experts to develop a novel method to identify biomarkers for sickle cell disease. During my PhD and postdoctoral career, I have received several awards and grants, demonstrating an ability to secure external funding and interest in my research.

Teaching Interests:

In addition to research, I have a keen interest in mentoring students and teaching core as well as advanced engineering topics. During the tenure of my PhD I was a teaching assistant (TA) for several courses including: Transport phenomenon-I, Junior design and economics, and Process control. As a postdoctoral research fellow, I have co-instructed a Health Science and Technology course (Matlab for Medicine) for medical students, which is a required core course for the Harvard-MIT MD curriculum. I have derived immense pleasure from teaching and helping undergraduate students learn the chemical engineering curriculum. During my PhD tenure, I have mentored more than five undergraduate and masters students, who have successfully performed research and have co-authored publications in leading peer-reviewed journals. During my postdoctoral training, I have helped supervise two graduate rotation students and an undergraduate summer intern, as well. I have always encouraged undergraduate students to pursue research in addition to their coursework. I am very comfortable with teaching the core chemical engineering subjects, and I would be very excited to design additional courses that combine the knowledge of chemical engineering, mathematics and statistics.
