                   Field Technical Support Manager, providing field technical and applications support for their clinical AuRICA cytometric human A.I.D.S. diagnostic CD4 analyser. This novel system uses colloidal gold micro-particles as a simple assay for CD4 on lymphocytes, detected by changes in side-scatter signals. The entire assay is performed within the fully enclosed instrument automatically and can be operated by relatively inexperienced technicians, such as often are found in Third World cuntries. Based just outside Boston and covering the entire globe, especially focusing upon sub-saharan Africa and the Caribbean. This involved substantial travel to countries including Kenya, Nigeria, Tanzania and Haiti, to provide technical support in multiple rural bush clinics and hospitals. Substantial involvement in the winning of a major World Bank award, for the development of a mobile laboratory vehicle, to provide travelling analytical services to H.I.V. patients in their rural bush communities in Malawi. Fist author of a S.B.I.R. grant application, to develop a novel simple cytometric assay for liver toxicity, often caused after prolonged anti-retroviral drug therapy.

(Personal Cell Analyser), P.C.A.-96 automated screening cytometer and P.C.A.-96-A.F.P. blue laser system. Based in Boston and covering the U.S. North Eastern territory, from New York City up to Canada and west to Buffalo. Guava is a biotechnology company, which develops, manufactures and markets patented, integrated cellular analysis systems, for the life sciences. The company is changing the way in which cell culture monitoring and cell screening assays are performed, by providing compact micro-volume scale systems that make common assays in cell-based analysis accessible directly at the bench. Guava’s products have broad applications to life sciences research, drug discovery and biopharmaceutical production, but also offer potential for use in clinical testing and blood processing, as well as other areas where simple, single cell analysis is important.
