A full-time Research Assistant position in Molecular Biology/Genetics is available in a multidisciplinary team led by Dr. Diako Ebrahimi and Dr. Smita Kulkarni. The qualified candidate will be working on projects related to virology and cancer. The Research Assistant will be applying molecular and cellular biology/virology techniques such as DNA/RNA extraction, infectivity assays, CRISPR, Western Blots, and sequencing to understand the molecular determinants of viral and cancer mutagenesis.

Texas Biomed provides unique research and training opportunities for its employees, including access to exceptional resources such as BSL4, SNPRC (Southwest National Primate Research Center), a vigorous infectious disease program on HIV, malaria, schistosomiasis, Ebola, Zika, hepatitis C and TB, and outstanding imaging, computational, and sequencing facilities. Texas Biomed faculty have adjunct appointments at two universities in San Antonio (UTSA and UTHSCSA), which provide a wide range of additional training and career development opportunities for employees at Texas Biomed.
