I build electronic, microscopy, and software tools for observing and interfacing to large scale mammalian neural cultures in an effort to better understand neuronal computation and build the next generation of neural interface devices. Through my experiments I also hope to understand the nature of nervous system development, evolution, and information processing so that I may smooth the accelerating integration of humanity with its technology.
As a former molecular biologist, analyst of the aging biotechnology industry, and current bioengineer it is my opinion that classical biotechnology (biochemistry, molecular biology, drug development, etc) is facing huge compexity problems and running into several dead ends in getting at the problem of human aging.
The critical fields where progress is necessary for altering human aging include general systems theory, general and machine intelligence, information theory, mathematics of complex nonlinear dynamics, tissue engineering, materials engineering (including nanomaterials), neuromorphic engineering, semiconductors and computational hardware in general, and of course (
bias noted) neural interface engineering.
Molecular biology is of course useful as a tool, but it is reaching its limits as far as explanatory power. I think the most productive direction to move towards are hybrid fields such as bioengineering or systems biology. Any good bioengineer or systems theorist should be able to count MoBio as part of the their set of tools, but it is more often than not a means to an end.
The reason I moved away from the traditional biomedical sciences was that it became very clear to me that "better than original" tissue systems would be possible to design much more easily than trying re-engineer existing organic systems for longevity and upgradability, given all of the built-in legacy problems associated with biological systems. In short, interfacing components which give additional functionality to human beings are possible now, while wholesale redesign (which is what I believe will be necessary for greatly extended longevity) will still be a while in coming. We should use biology as teacher, but should not make its limits our own.
