PhD in Chemical Engineering

About Me

Industrious chemical engineering graduate with several years of analytical chemistry research experience at Takeda Pharmaceuticals. I am seeking to apply my unique skill set in the area of process design and chemical engineering fundamentals to the development of novel chemicals.

Work Experience

City College of New York
Graduate Research Assistant, Chemical Engineering
August, 2012 - Present
  • Synthesized and characterized bimetallic heterogeneous precious metal catalysts for steam reforming oxygenated fuels.

  • Performed catalytic ethanol steam reforming using isotope-labeled reactants to gain insight into dominant reaction pathways and the contribution of each metal to reforming behavior.

  • Developed models of thermodynamic and kinetic parameters for the catalytic steam reforming of ethanol using Matlab.

  • Catalyst performance analysis by gas chromatography (GC) equipped with thermal conductivity detector (TCD) with simultaneous X-ray absorption fine structure (XAFS) analysis using the National Synchrotron Light Source I at Brookhaven National Laboratory monitored in situ and operando changes to the catalyst surface during reaction.

  • Purchased and maintained analytical equipment including an Agilent 7890B GC system with TCD, ECD, and Agilent 5977A mass selective detector (MSD), Inficon 3000 Micro GC, and Quantachrome ChemBET Pulsar TPR/TPD Automated Chemisorption Flow Analyzer.


Golden Renewable Energy
, Research Collaborator
January, 2015 - January, 2017
  • Performed onsite emissions testing on a commercial scale renewable diesel fuel and syngas production reactor processing waste plastics grades 1-7.

  • Determined the composition of syngas produced during processing to evaluate energy content.

  • Developed GCMS method to detect and quantify liquid product fraction of commercial scale renewable diesel fuel and syngas production reactor.


Université Catholique de Louvain
, Postdoctoral Visiting Researcher
November, 2016 - January, 2017
  • Characterized novel Ni-based catalyst for methane reforming.

  • Performed intrinsic kinetic study for the catalytic steam reforming of methane.

  • Developed simulation of reaction taking account on non-idealities in transport and temperature gradients.


Takeda Pharmaceuticals
, Research Associate, Analytical Development
June, 2009 - August, 2012
  • Developed analytical methods to characterize new oncology drug candidates using GxP laboratory practices. Used Empower 2 and Chemstation for the control of high performance liquid chromatography (HPLC), GC with flame ionization detector (FID) and MSD, and Karl Fischer moisture analysis instruments reduced analysis time by a factor of at least two.

  • Contributed to the development of a dissolution method for solid oral formulations of new drug candidates allowed for rapid determination of variability between batches and provided a basis for in vivo kinetic modeling.

  • Performed lab-batch testing for preclinical and clinical drug products contributed to the advancement of new drug candidates through all phases of clinical trials.

  • Container-closure system study performed on pediatric oral formulation of drug candidate. Unanimous decision to proceed with one particular configuration based on my recommendation. Received internal recognition for outstanding work on this project within the Millennium Star Award Program.


College of the Holy Cross
, Research Assistant, Department of Chemistry
May, 2007 - May, 2009
  • Developed a method for rapid determination of coating performance in capillary electrophoretic (CE) separations reduced qualification time by a factor of six.

  • Contributed to the development for a universal coating for microchip and CE separations using a Beckman-Coulter PACE/MDQ Capillary Electrophoresis instrument with UV detection - resulted in consistent, reproducibly uniform coatings allowing for higher throughput analyses.

  • Trained new lab members on the various equipment used in day-to-day laboratory activities.
