Jin Huk Choi, Pharmaceutics graduate student, presented preliminary data and a plan for completing his research project titled "Evaluation of the Oral Mucosa as a Site for Protective Immunization Against Ebola Zaire with an Adenovirus Serotype 5-Based Vaccine" to his committee members which they agreed was quite novel and would provide significant insight into vaccine development for Ebola and other pathogens. That same day, he left for the Immunological Mechanisms of Vaccination meeting and presented his work on a sublingual vaccine for Ebola to international experts in the field the following day.


October 2010 Dr. Croyle Travels to the National Institutes of Health to Serve on Several Study Sections.

Dr. Croyle provided expertise in the area of drug and vaccine development and the design of in vivo studies to a scientific panel at the NIH in an effort to evaluate research proposals for funding.


September 20, 2010 Dr. Croyle Travels to the Public Health Agency of Canada to Celebrate Completion of Collaborative Nasal Vaccine Project with Drs. Gary Kobinger and Amine Kamen.

Dr. Croyle presented her work on the formulation and characterization of a nasal vaccine for Ebola to officials from the Canadian Chemical, Biological, Radiological-Nuclear and Explosives (CBRNE) Research and Technology Initiative (CRTI). Dr. Kobinger discussed work from his group in characterizing the immune response and potency of the formulated vaccine. Dr. Kamen then discussed the efforts of his group to develop an efficient large-scale production method for the vaccine. Overall, the project was considered to be a success and a proposal for clinical testing of the vaccine in Canada will be submitted in early 2011.


July 23, 2010 The Croyle Lab Participates in the University of Texas Honors Colloquium.

Dr. Croyle met with approximately 40 honors students from high schools throughout the state of Texas to discuss her work on an Ebola vaccine. Stephen Schafer, and Jin Huk Choi then conducted a lab tour. Students were shown first hand how the vaccine was made in cell culture and the various assays that must be performed on the preparation before it can be used in scientific studies.

July 23, 2010 Piyanuch Wonganan defends her thesis!

After 5 years of hard work, Piyanuch Wonganan defended her Ph.D thesis titled "A Mechanistic Study of How Adenovirus Infection Alters the Expression and Function of Cytochrome P450 3A". After graduation, Piyanuch plans to return to her home in Thailand and assume a faculty position after completing a postdoctoral research fellowship in the United States.


June 22-23, 2010 Dr. Croyle attends International Filovirus Medical Countermeasures Workshop.

Dr. Croyle participated in a joint meeting of the scientific community involved with the development of therapeutics for filovirus infection, the department of defense and other funding agencies that support their work. The purpose of the meeting was to identify current hurdles that prevent research in this area from progressing.


June, 2010 Stephen Schafer wins UT College of Pharmacy Staff Merit Award.

Mr. Schafer was recognized for his dedication, service, and outstanding job performance at the annual College of Pharmacy Staff luncheon held at the Broken Spoke Saloon where attendees were treated to a traditional Texas meal, took part in country-western dance lessons, and enjoyed the music of Gary P. Nunn. Later that month, Stephen was promoted from Laboratory Technical Services Supervisor to Program Coordinator for the Croyle lab for all his hard work.


April 27, 2010 Dr. Croyle travels to the Massachusetts Institute of Technology to Review Grant Proposals for the National Academy of Finalnd.
