Dr. Marcela Hernandez is the Administrative Director in the Office of Postdoctoral Affairs at The Ohio State University. She received a Bachelor of Science, in Molecular Genetics, and an M.S. and Ph.D. in Biochemistry.  Her scientific training and research in biochemistry and molecular biology focused on control of gene expression at the transcriptional and posttranscriptional levels. Her role is to design and implement programs to enhance retention, and support of postdoctoral scholars including a special focus on those with underrepresented backgrounds. She became a scientist thanks to an excellent Ph.D. mentor who inspired her, trained her, and mentored her. For this reason, she is very passionate about mentoring and is working to help the next generation of STEM professionals navigate successfully to rewarding careers. Dr. Hernandez is also the mother of twin boys, one of whom has learning disabilities, which has made her active in the area of support and advocacy of students with disabilities at the K-12 and college levels.
