TECHNICAL PROJECTS

Directed evolution to engineer a methanol tolerant lipase for biodiesel synthesis Protein Engineering December 2019

● Designed Burkholderia cepacia lipase that is methanol tolerant by introducing disulfide bonds and using iterative saturation mutagenesis and immobilization.

● Analyzed the effect of the mutation on the finally derived lipase using X-ray crystallography and analyzing transesterification.

Constructed a Composite for Efficient Photocatalytic Reduction of CO2 Heterogeneous Catalysis December 2019

● Pioneered a methodology for the synthesis of the 3-layered composite zeolite (i.e. a-Titanium oxide Zeolitic imidazolate-67 halide perovskite) to obtain stability, visible light absorption, and efficiency to convert CO2 to CO or ethanol

● Characterized the material produced and efficiency using different methods such as XRD, SEM, TEM, FTIR spectroscopy, etc.

Perovskite Solar Cells Team Leader

Transport Phenomena May 2019

● Led team to develop a diffusion model for electron-hole transport in thin-film perovskite solar cells.

● Analyzed the parameters using different model p-i-n and n-i-p configurations along with experimental data to determine the parameters which limit the cells’ efficiency. Predicting molecular weight distribution for higher density poly-olefins Polymer Science & Reaction Kinetics May 2019

● Perused and simulated simple core model on Matlab for determination of molecular weight of olefins

● Using the central hypothesis that all the particles in the multigrain model are equivalent in size predicted the molecular weight distribution of poly-olefins using MATLAB Algal Photobioreactor for CO2 mitigation

Undergraduate Thesis June 2016

● Developed a laboratory-scale algal photobioreactor and studied the effect of different parameters such as light (wavelength, intensity), pH, gas flow, algal species on biomass growth.

● Using the biomass data analyzed the amount of CO2 that can be fixated, sequestrated, and mitigated. Zein Based Biofilms for Food Packaging

Bionanotechnology May 2020

● Biomimicked the lotus effect to create templates that were imposed on zein-based films (made from corn protein flour) providing them superhydrophobicity, antibacterial, mechanical, and gas/water barrier properties.

● The films produced were analyzed using Fourier transform infrared spectroscopy and scanning electron microscopy.

A Novel Methylene Chloride Removal Method

Air Pollution Sources & Control May 2020

● Introduced a novel method to remove methylene chloride, a non-significant air pollutant defined by EPA and OSHA using an Air Lift Packing Reactor (ALPR).

● Studied the implications, effects, and societies at risk due to this air toxic pollutant and related separation techniques.
