From Mathematics To Bioinformatics

During his undergraduate years, Dr. Altschul developed an interest in Biology. As a result, he started reading books about DNA. One of the books which he read was "The Double Helix" by Watson. Furthermore, he had also taken course on Evolutionary Biology. Dr. Altschul had also spent two summers working in laboratories at Rockfeller University where he helped to write computer codes for a X-ray crystallography project.

Due to his interest, Dr. Altschul had considered trying to apply to graduate school in Biology. He instead decided to apply to programs in applied mathematics, with the hope of finding some applications of mathematics to biology to work on.

Notable Appointments/Positions Held

Upon graduation, Dr. Stephen Frank Altschul worked in the Mathematics Research Branch of the National Institute of Diabetes and Digestive and Kidney Diseases as a IRTA postdoctoral fellowship.From 1990 to present, he works in NCBI Computational Biology Branch, holding the position of senior investigator.

Research Interest

His research interest is centered around sequence alignment algorithms, statistics of sequence comparison and measurement of sequence similarity.
