Laser microsurgery – Dr. Berns’ research centers around studying basic cellular problems from a functional and structural point of view. Dr. Berns’ laboratory has developed and combined sophisticated techniques and instrumentation such as lasers, computers, light and scanning EM to study a variety of problems:
- mechanisms of chromosome movement and spindle fiber organization
- cell movement
- structure and organization of chromosomes, nucleoli, and mitochondria
- cardiac cell contractility
- cellular carcinogenesis and cancer diagnosis and treatment
- biophysics of light interaction with cellular systems
- laser applications in clinical medicine (oncology, surgery, cardiology, ophthalmology)
- computer enhancement of optical images for cell biology, genetics, and clinical medicine.
In addition, a major emphasis of the program is to facilitate the application of basic laser research to problems of the real world. This is accomplished by creating linkages between the laser program and a variety of industrial associates who translate the research into viable technology in the health and biotechnology field.
