The main focus of my research has been experimental until recently. In collaboration with Dr. Miguel Garcia-Garibay’s group at UCLA, I investigated methyl group dynamics in relation with tunneling mechanism in photochemical reactions, photochemical reactions in zeolites as well as enantiomeric interactions in zeolites by means of Nuclear Magnetic Resonance (NMR), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Gas Chromatography, Mass Spectrometry (GC-MS). However, in the past year my research interests have shifted to computational chemistry which has been growing in importance in the past decades, as acknowledged by Nobel prizes awarded in 1998 and 2013. Computational Chemistry is a powerful tool which provides a microscope into the behavior of molecules and materials at atomic level and is becoming an extremely powerful tool for gaining insight into chemical processes otherwise difficult or impossible to obtain from experiments. It can also be conducive to valuable interdisciplinary collaborations with mathematics and biology professors and students. For example, computational projects provide research opportunities for mathematics students as well as students in physical and life sciences.
One of my research projects is on investigating how amino acids get adsorbed into zeolites using MD and Monte Carlo Simulations. This project is in collaboration with Dr. Arno Papazyan. The goal of this project is to complement my experimental results in finding a new avenue to enantiomeric enrichment in an achiral medium provided by zeolites which are aluminosilicate cages with adsorption capabilities. The separation of one enantiomer from the other is a very important practical issue in medicine today because the incorrect enantiomer is either useless or may cause detrimental side effects. It also lies at the origin of life, since most of biochemistry involves chiral molecules. Our research efforts are towards making a significant and fundamental contribution to our knowledge about the repertoire of processes leading to enantiomeric purity.
My other research project focuses on the theory of Nuclear Magnetic Resonance (NMR). This project is in collaboration with Joshua Helston and Dr. Alan Benesi. The goal for the mathematics and mathematically inclined chemistry and biochemistry students is to learn the mathematics underlying Nuclear Magnetic Resonance (NMR), which is a very important and useful technique in science and medicine, forming the basis of several Nobel Prize winning discoveries, with Nobel prizes awarded in 1946, 1991, 2002, 2003, and inventions, including the life-saving Magnetic Resonance Imaging (MRI) technology. NMR can probe into the nuclei of atoms and inform us about molecular structures and environments, motions, proximities of atoms, and rates of reactions. Using algorithms in Dr. Alan Benesi’s new book “A Primer in NMR Theory with Calculations in Mathematica” we are simulating the rotation rates of deuterium nuclei for water in gypsum at various temperatures. We have been able to investigate the molecular motion of D2O in gypsum, which has fire-retardant properties due to the water molecules in its crystals. Understanding molecular motion is crucial for reactions and properties of molecules.
My research group includes chemistry, mathematics, biochemistry and biology students. We showcase our work in several scientific conferences at Mount Saint Mary’s University and elsewhere such as the American Chemical Society (ACS) Meetings, The Experimental NMR Conference (ENC), The Southern CA Conference of Undergraduate Research (SCCUR), and the Southern CA Users of Magnet (SCUM) meetings. My research students have been accepted to Ph.D, PharmD, DPT Programs at prestigious universities such as John’s Hopkins, Texas A&M, UCLA, and University of Madison Wisconsin, UCLA, UCR, USC, Touro University and KGI of Claremont etc.
I am very active in the NMR community throughout Southern CA. I am the founder of the Los Angeles Area Magnetic Experts (LAME), which expanded to Southern CA becoming, the Southern CA Users of Magnets (SCUM) Meetings.
I am also invested in women’s success in the STEM fields as I was invited to act as moderator at the Berkshire Conference in June 2017, for a session entitled “STEM Education in Japan: Examining the Professionalization Pipeline for Females”. This roundtable session included prestigious scholars on the subject, such as Dr. Yuko Takahashi, President of the first Women University in Japan, Tsuda University, Dr. Yuko Itatsu, from The University of Tokyo and Dr. Diane Rodriguez-Kiino, from California Lutheran University.
