Collins identified potential anti-HIV-1 activity in a number of partially purified plant extracts, especially Chrysanthemum morifolium, Salvia miltiorrhiza, Prunella vulgaris and commercially available supplements, i.e. polysaccharopeptide (PSP) from Trametes versicolor.[2][3][14] He represented a biotechnology company in discussing the scientific validity of the method proposed by the Government in the Bills Committee stage of the proposed legislation[15] and the media.[16]
As a result of the growing interest in genetic parentage testing (DNA profiling) in Hong Kong, Collins, working with others, found that the number of men in Hong Kong who were not the biological fathers of their children might be much higher than expected.[17][18][19]
Collins also helped develop a number of rapid diagnostic tests based on nucleic acid analysis, notably the nucleic acid sequence-based amplification (NASBA) technique. Many of these were developed in response to high-profile disease outbreaks in Hong Kong and around the world, e.g. avian influenza H5N1, H7, foot-and-mouth disease, severe acute respiratory syndrome (SARS). Collins has given numerous presentations and interviews to scientists and the media to support the development of the new tests.[20][21][22][23][24][25]
Currently, Collins is scientific review director in the Research Office of the Food and Health Bureau, Hong Kong SAR Government, where he is involved in managing public funds related to health services and infectious disease research. His recent interest is in assessing the payback from research supported by public funds.[26]
