Team hopes to cut years off development time of new antibiotics
Date:2/11/2011

es only time will tell its effectiveness. Tam and Nikolaou, however, are employing computer modeling and simulation to project how bacteria would respond to different exposures of a drug, focusing on how much medicine a patient should take, how often it should be taken and for how many days. Subsequent investigations in clinical studies can then target those dosing methods that have the highest probabilities of success.

Tam, an expert on experimental therapeutics, and Nikolaou, with a background in computer-aided systems engineering, forged their collaboration through a seed grant from UH before they attracted external funding. Their modeling approach relies on fundamental laws of nature, which are exploited to generate future projections from scant experimental inputs through computer simulation. This has been demonstrated to be better than simple human eyeballing.

"Our approach gives us the ability to take extra variables into consideration in an attempt to develop a more robust computational tool that covers a wider spectrum of relevant scenarios in new drug development," Nikolaou said. "Some pharmaceutical companies are following our developments closely, and we are in the process of refining a model prototype in the form of a computer program to ultimately be used in a clinical setting."
