DAVID HULL, SENIOR RESEARCH PROFESSOR

Dr. Hull joined Valpo's faculty in 1983, and he recently presented his paper "Elementary proofs for certain extinction in bisexual Galton-Watson branching processes" at the Workshop on Branching Processes and their Applications in Spain.

As senior research professor, Dr. Hull plans to continue his research on the mathematical model for the bisexual Galton-Watson branching process in conjunction with colleagues at the University of Extremadura in Spain. Dr. Hull was invited to speak at an international conference in Bulgaria following his recent presentation in Spain, and his research will consider simplifying the proofs of known theorems for certain extinction, developing theory regarding the time to extinction and applying the bisexual process to Mendelian genetics.
