Research Interests:

Research experience:

I am a Chemical Engineer by training and have worked on a wide variety of research projects in various realms of basic sciences and engineering. The common denominator across all my research experiences is mathematical modeling and systems engineering. The multifaceted areas of my expertise include working on non-linear system dynamics pertaining to reaction engineering, developing mechanistic mathematical models for improving processes operation in pharmaceutical drug manufacturing, and clinical data analyses related to human pathophysiology.

During the course of my research expedition I have been interested in diverse fields in which 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, I worked closely with my experimental colleagues for developing realistic mathematical models and to better understand the underlying assumptions required for a specific model. Furthermore, I have had opportunities to become adept in various hands-on laboratory techniques including the use of a fluidized bed granulator. Towards the end of my PhD, I got drawn into the enigma of systems biology, which led me to switch fields and broaden the applications of my mathematical modeling skills.

Currently as a postdoctoral research fellow I work in an extremely multi-disciplinary environment with clinicians, biologists, chemists, engineers, and statisticians. I am leveraging my engineering training to develop models that can improve disease prognosis and alleviate the shortcomings of a delayed therapeutic intervention. Moreover, I am collaborating with experts in the field of microfluidic device development with the aim of developing a point-of-care system to detect biomarkers for sickle cell disease using single-cell measurements.

Throughout my PhD and postdoctoral journey I have received several awards and grants that exhibit my ability to secure external funding and inculcate others’ interests in my research.

Research Vision:

I plant to integrate my training in various fields of engineering and medicine, with a special focus on systems engineering, by developing tools that describe hematological systems and particulate processes. In the short-term, I aim to develop data-driven population dynamics models for blood cells to predict the occurrence of diseases. Furthermore, by using this approach I intend to develop hypotheses for the underlying mechanisms of diseases. These hypotheses in turn will be investigated by performing laboratory bench experiments. I plan to integrate these models for various lineages of white blood cells in order to investigate the crosstalk within the immune system. Additionally, I plan to develop models (macroscopic, microscopic and mesoscopic) for quantitative systems pharmacology and then consolidate the dynamic behavior of the various components to study the overall pharmacodynamic behavior of the human body.

From a process systems perspective, I aspire 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.

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. I have derived immense pleasure and a sense of accomplishment from teaching and helping undergraduate students learn the chemical engineering curriculum. I have mentored several undergraduate and masters students, who have successfully performed research and have co-authored publications in leading peer-reviewed journals. I have persistently encouraged undergraduate students to pursue research in addition to their coursework. I enjoy teaching the core chemical engineering subjects and am extremely excited to design and teach new courses that combine the knowledge of chemical engineering, mathematics and statistics.
