He was elected as Confrerie des Chevaliers du Tastevin in 2000. When not immersed in Science, he relaxes by searching for Wagner’s leitmotifs, musing over Kandinsky’s chaos, and contemplating Wittgenstein’s inner thoughts. He obtained his B.S.E.E. degree from the Mapua Institute of Technology, Philippines, M.S.E.E. degree from MIT, and Ph.D. degree from the University of Illinois at Urbana-Champaign.
In this talk I will review several unsolved deep scientific problems that many luminaries, including Galvani, Boltzmann, Schrodinger, Prigogine, Gell-Mann, Eigen, Turing, Smale, Hodgkin-Huxley, et al., had spent much of the later part of their life, toiling in vain to solve them. For example, in 1781, Galvani was dumfounded when the exposed nerve of a frog leg he was dissecting suddenly twitched when hit by a spark from a nearby Leyden jar. Galvani has spent countless sleepless nights trying to explain the phenomenon by seeking for an "extremely mobile principle", which we now know is the local activity principle. Fast forward 100 years later, Boltzmann was struggling to explain how life could emerge, and concluded, in a qualitative way, that the "existence of animate beings is a struggle for entropy". About 60 years later, Schrodinger continued Boltzmann's incomplete quest with his discovery that what Boltzmann needs is "negative entropy" -- an intuitive but fuzzy concept that we can now identify as the existence of an edge of chaos domain. Prigogine continued Schrodinger's thermodynamic approach by proposing his "Instability of the homogeneous principle", which turns out to be astability condition that was misleading, and had actually impeded progress, when interpreted from the fine lens of the Edge of Chaos Corollary -- the pearl of the local activity principle. Gell-Mann came very close to the target when he proposed the holy grail to be the system's inherent " ability to amplify small signal fluctuations". He failed because he did not realize that the relevant physical variable to be endowed this small-signal gain property must be the local energy about an equilibrium state. To illustrate the universality of the local activity principle, I will touch base with Alan Turing, father of computer science and AI, in particular his contribution on the "Chemical basis of Morphogenesis". He was perplexed on how an embryo in its spherical blastula stage could break symmetry, without external forcing, to deform and grow into a non-symmetrical embryo. With great intuition, Turing devised a toy example of 2 identical cells each harboring 2 chemicals with concentrations X and Y, respectively. When uncoupled, the 2 chemicals in the 2 identical cells have identical concentrations, as expected. By applying trial-and-error, and intuition, Turing selected 2 different diffusion coefficients D(X) and D(Y) to couple the 2 identical cells. Although diffusion is a dissipative process, Turing's ingenious insight suggested the concentrations of the 2 identical cells would change, and the symmetry of the resulting reaction-diffusion equations was broken! Turing's choice of the 2 diffusion coefficients that led to symmetry breaking was based on his intuitive guess, because Turing did not have an algorithm for choosing the 2 dissipative coefficients that would guarantee symmetry breaking. This is the occasion where the edge of chaos criterion comes in handy, for it provides a simple "symmetry breaking" algorithm for calculating the 2 diffusion coefficients. I will present an example in this talk by choosing 2 identical first-order nano-scale NbO2 memristor circuits and couple them via a positive resistance, whose value is calculated via the Edge-of-Chaos Criterion such that the two identical first-order memristor circuits in the resulting reaction-diffusion equations have different equilibrium states. Indeed, I will follow Stephen Smale to couple two identical 2nd-order nano-scale NbO2 memristor circuits via 2 positive resistors calculated to be on their respective edge-of-chaos domain, and demonstrate to the audience that the symmetry of the resulting 4th-order reaction-diffusion equations is broken, resulting in a 4-dimensional oscillator.

University faculty and students often seek to collaborate with companies in research, internships, and bringing real-world perspectives to the classroom. This exposure can be very beneficial to students and also enhances the relevance of university research. Companies are motivated to engage with universities so that they have a prepared workforce and can tap into the intellectual creativity of the research. On the surface, it looks like a match made in heaven. In this talk, conversations with a few dozen company engineering leaders and university faculty from around the world will illuminate challenges faced while recognizing the tremendous synergies and opportunities. The goal of this talk is to plant seeds for how universities and companies around the world can chart a path that creates the win-win.

For decades, Moore's Law has delivered the ability to integrate an exponentially increasing number of devices in the same silicon area at a roughly constant cost. This has enabled tremendous levels of integration, where the capabilities of computer systems that previously occupied entire rooms can now fit on a single integrated circuit. It's well documented that Moore's Law is slowing on all its dimensions and corollaries. While improvements in density scaling continue at a reduced pace, the industry is simultaneously observing increases in manufacturing costs that are threatening to eliminate the cost per transistor generational improvement that has been fundamental to the value proposition of semiconductor compute products. In response to this existential threat to the industry, the solution is, as it always has been, to innovate.
This talk will focus on several compelling vectors of innovation that will enable our industry to thrive within the limits of physics and silicon scaling. The first is around extraction of more value from each manufactured transistor through modular chiplet architectures that enable application-specific choice of process technology and market-specific personalization of products. The second opportunity extracts more performance from each yielded transistor through targeted use of special purpose accelerators that provide dramatic efficiency gains over general purpose compute. Finally, there is the growth in applications of AI to all aspects of computing, making use of reduced precision accelerators that add non-linear value to compute capabilities and user experience in all key market segments. Putting all these together with the right software solutions will provide synergistic improvements in compute capability that can enable a thriving industry for the foreseeable future.
