Greater Atlanta Area

Professor of ChemistryCourses Taught:- General Chemistry (Lecture and Lab)- Instrumental Analysis (Lecture and Lab)

Birmingham, Alabama Area

- Taught General Chemistry 1&2 Lab classes (CH 116 & CH 118).- Developed a new research-based honors chemistry course (CH 117 & CH 119) where students were able to present guided research in symposiums.

Birmingham, Alabama Area

- Completed a PhD in Polymer Chemistry with a focus on targeted Theranostic Drug Delivery with a focus on micro-particles.- Developed a polymer-based microparticles for use in theranostic drug delivery utilizing ultrasound medical imaging and delivery. Utilizing layer-by-layer polymer architecture, non-invasive targeted drug delivery was achieved in cell.

Optimized the growth of multicellular tumor spheroid clusters of Hep G2 cells (liver carcinoma) by using cellular-material interfaces in fabricated environments. Methods included “hanging drop” and PDMS (Polydimethylsiloxane) fabricated bases.

Greater New Orleans Area

Worked with Dr. Arthur Lustig, and performed cell assays of TRD-1-9c yeast transformed with A40t vectors to measure the drift over generation in telomere length, and the ability to bypass senescence. Performed yeast culture and DNA isolation techniques, and Southern Blotting.

Greater New Orleans Area

Worked with Dr. Su-Chen Li, and assisted in laboratory experiments for blood type conversion. Used enzymes to successfully convert blood type B into blood type O with the ultimate goal of universal donation. Gained skills in blood type identification, gel electrophoresis microspectroscopy, and data processing and presentation.

Greater New Orleans Area

Worked with Dr. Yu-Teh Li, and assessed whether sample ovarian cysts were malignant or benign based on protein assay. Assisted with laboratory procedures, including spectophotometry, lyophilization, thin layer and column chromatography, fractionization of samples, and data recording.
