Contribution to Science

1 - My previous research has been to understand the chemistry of the key intermediates that mediate the biological effects of mutagenic and carcinogenic nitrosamines. Nitrosamines are a large class of compounds to which there is human exposure through endogenous formation and environmental sources. They are found in groundwater, foods, personal care products, and tobacco products and are encountered in a number of industrial environs, in particular in rubber manufacturing and curing facilities, metal and leather working concerns. They tend to target the oxygen atoms of DNA by means of adducts they form and cause replicative polymerases to mis-insert opposite these lesions leading to mutation.
My work involves modified phosphoramidites synthesis and their characterizations. I have developed new methods for various nucleoside crosslink standards synthesis, their characterizations and derivatizations. I established new route for 13C labeled precursors in cross-link mimic, and their introduction into oligonucleotides for NMR studies. I have supported chemistry process with methods for reaction monitoring regarding purity/yield and analytical studies. We have explored sequence-specific recognition of nitroso derived adducts of minor groove of DNA and determined the effect of various factors on crosslink formation. Through our collaborations, we have studied the mutations spectrum in human fibroblasts which have attracted some research groups.

2 - My major contributions have in the area DNA base modifications of oligonucleotide conjugates. The subject is of general importance, since accumulation of DNA base moieties induced by environmental contaminant, food additives or oxidizing atmosphere constitute an increased risk of cancer. I developed several methods useful for syntheses of such structurally modified constituents of DNA and studies of their properties and mechanisms of formation. In particular, his studies has advanced the understanding of the ability for 1,3-dicarbonyl compounds and their congeners to form cyclic adducts of nucleobases. Such compounds are produced intracellularly as end products of the catabolism of peroxidated fatty acids of cell membranes. Cell membrane peroxidation, in turn, is a consequence of oxidative stress caused by increased level of ozone and peroxidated organic acids in urbanized regions.

3 - My understanding of bioorganic chemistry has given me the opportunity to teach biochemistry even as chemistry major. Through my research, I have developed multi-step synthesis protocol for halocarbonyls, halodicarbonyls, tricarbonyls, and nitroso compounds. Some of these synthesis have found their route into industry and are used for big scale production.

Abstract

Abstract This project developed small, portable sensor-based experiments as an alternative to those conducted in a traditional laboratory setting. Experiment-centric pedagogy was used in this study and hands-on laboratory experiments were developed using USB-based measurement devices (ADALM 1000) and ADALM2000). Three experiments were developed for Chemistry namely pH meter, thermochemistry, and spectrophotometry. During pH settlement, the voltage was recorded, and the calibration curve drawn using standard buffers 4, 7, and 10. Furthermore, thermochemistry results were performed and validated using a digital thermometer. R2 curves have been found to yield good results for both experiments. Department of Transportation worked on four experiments which include vehicle counter, accelerometer, decibel meter, and a soil moisture meter. Data was recorded from each setup. Since the sensors provided results as voltages, a transfer function equation was used to convert the reading to the required unit of expression to validate the results from the USB device.

These experiments were developed by pairing a graduate student in electrical engineering with a student in another discipline during a 10-week summer workshop. Student trainees underwent different training sessions that comprise of developing and testing instruments for measurement, attending the ASEE virtual conference, and research workshops. Students also read and summarized articles on the use of experimental pedagogy to motivate students.

This study is designed to improve outcomes for students in the chemistry and transportation departments using laboratory activities.
