Dr. Peggy Putnam Alexander
Applied Clinical Research: Course based teaching duties for traditional dental students including DS3 and 4 Patient Management, DS 2 and 3 Restorative Dentistry
Biomaterials Evaluation: Assessments of diagnostic adjunctive devices for use in implant placement
Dental Implant Prosthetics: Evaluation, restoration and management of dental implants in select group of patients
Etiology of Dental Erosion: Extensive exploration of cultural and behavioral contributions to the loss of tooth structure. Included in this study are mechanisms for intervention and restoration of function
Implant Placement and Restoration: Involved in research comparing healing characteristics of dental implants in persons who are Type 2 Diabetics with controls
Periodontal Disease and Type 2 Diabetes: Examiner in multicenter, randomized, controlled, single-masked Phase III designed to determine if non-surgical periodontal therapy is efficacious in reducing elevated glycosylated hemoglobin (HbA1c)
Dr. Devjit Tripathy
UT Heath Science Center School of Medicine and staff physician and director, Diabetes Research Unit, Bartter Research Unit, Audie L. Murphy VA Hospital
Botnia Clamp Technique: He described and validated a new method for assessing insulin sensitivity and insulin secretion during the same test- the Botnia clamp (Tripathy et al. Independent measures of insulin secretion and insulin sensitivity during the same test: the Botnia clamp. Diabetes Care 26:1395-401; 2003), which is being used by several investigators.
Pathogenesis and Treatment of Type 2 Diabetes: Molecular mechanisms of insulin resistance and the mechanism of action of newer anti-diabetic agents. The diabetes research unit is one of the busiest units in the world where a large number of hyperglycemic and euglycemic insulin clamp studies are performed and I supervise and routinely perform these studies. In addition He performs skeletal muscle biopsies during the clamp studies to study insulin signaling in the muscle which requires special expertise.
Adriana Vargas Green
Dr. Vargas Green is a general dentist with specialty training in geriatrics, medically compromised patients, and post-doctoral advanced training in hospital dentistry. She received a Master of Public Heath degree from UTHSC-Houston in 2010. Her main focus at the UTHSCSA Dental School is in teaching and service. She is involved in multiple teaching activities supporting undergraduate and graduate programs.
In her current position as an Associate Professor with Tenure and Assistant Group Leader. My main responsibility is clinical instructor to junior and senior dental students. This involves clinical teaching supported by evidence-based dentistry and scholarly activity for the students such as literature searches and referencing books. She provides administrative management to junior students, ensuring they complete the clinical course expectations. She teaches and supervises the provision of dental procedures in all aspects of dentistry. For senior dental students she teaches immediate assessment, diagnosis, and present a primary treatment plan. She serves as a faculty advisor and student project mentor for pre-dental students, pre-doctoral dental students, and post-doctoral students. Her direct student contact time in teaching and patient care is eight half-days per week. She served as a course director for Heroes for the Homeless from 2008-2011. This course was offered to senior students as a selective. The course teaches cultural competency relative to oral health needs of the homeless population. She also collaborates in a Research project since 2003- to date in the Department of Periodontics looking the long=term healing of the dental implants in diabetic patients control and uncontrolled.
