I provide modeling and simulation expertise and support to various projects. My research tasks have centered on studying and developing mathematical models to examine negotiation approaches between two parties, using statistical analysis to understand the spread of COVID-19 during a natural disaster, studying mathematical models in the application of autonomous surface vehicles to support the Coast Guard, researching mathematical models that study blast injury on the human body, conducting exploratory analysis on data to infer properties of the data set, and study methods of risk assessment. I am also currently studying machine learning techniques to aid in the decision making process.My top accomplishments include developing an Excel toolkit that conducts a risk assessment on the successful transition of technology and utilizing the value iteration method to model negotiation tactics between two parties as a Markov Decision Process.

I examined the effects of surfactants in a binary mixture on interfacial tension and viscosity bydeveloping an accurate mathematical description of the system.

Gaithersburg, Md

I continued my work from my first postdoc with the NRC to investigate numerical schemes for the solution of generalized Ginzburg-Landau equations in thin film geometries and analyze numerical results for the development of defects in smectic C* (SmC*) liquid crystals (LC). I published a paper on this work.

Catonsville, Md

I taught Calculus 1 during the Fall 2017 semester and Summer 2018 session. I taught, along with another colleague Calculus 2 during the Spring 2018 semester.

Washington D.C. Metro Area

As a SETA contractor, I provided mathematical support in the classification, evaluation and investigation of existing and emerging technologies, systems and capabilities for the Department of Homeland Security (DHS), prepare and review project schedules, meeting minutes and procurement documents, and aided in the implementation of Earned Value Management (EVM) techniques to monitor the status of various projects.

Mentor: Dr. Geoffrey McFaddenI analyzed numerical schemes for solutions to a generalized two dimensional Ginzburg-Landau equation in thin film geometries using the Euler-Lagrange equations of these solutions. I developed a MATLAB code that solves the equations and predict the location of the number of vortices within the thin film geometry when the energy is in its lowest state. I began researching a diffuse interface model that describes the mixture of two immiscible fluids where mixing can occur at the interface, while incorporating various interfacial properties. I used variational calculus to study the equilibrium and stability of toroidal liquid drops on a conical substrate.

West Lafayette, In

I was a lecturer for a mathematics for elementary educators course (MA 13800) and a grader for two undergraduate differential equation courses

Purdue University

My dissertation involved analyzing a mathematical description of a thin film liquid crystal (LC) with ferroelectric properties. Given the model, it was possible to determine the number of vortices, the behavior of the molecules near the vortices, and their locations within the domain that is away from the boundary. A Matlab code was developed that computationally models the LC model description and uncovers new properties. One paper and a section of another paper resulted from this work.

Purdue University

I had various teaching roles as a graduate student. I was a lecturer for an Elementary Education Mathematics course for the Fall 2011 semester. I was a lecturer for a first and second semester Engineering Technology Calculus course for the Fall 2009 Spring 2010 semesters respectively. I was a grader for two undergraduate Real Analysis courses for the Fall 2008 semester. I was a lecturer for a College Algebra course for the Spring 2008 semester. I was a recitation instructor for a freshman Engineering Calculus course for the Fall 2007 semester.

Fort Lee, Va

I helped develop Bayesian Networks that will present the best probabilistic action to carry out when a particular scenario occurs. This will help decision makers with taking the best course of action based on current information in the field.

Quantico, Va

I performed detailed analysis of security products by writing software to execute specialized calculations to assist in the analysis and authored two documents accepted into Information Technology Division (ITD) technical literature.

Cambridge, Ma

I developed a mathematical model for the response of the polymer polypyrolle (PPy) under constant stress and to estimate the strain to charge ratio to determine if PPy have features of an elastic solid and a viscous fluid. This model accurately described the experimental data at low stresses, but not higher stresses and a better model needed to be developed.

Lancaster, United Kingdom

I performed statistical analysis in R to determine the correlation with the introduction of a new medical treatment and the decrease in the infection rate of external fixators. The analysis showed strong evidence that there was a decrease in the infection rate, but further test trials are needed.
