Talk Title: Efficient Management of Energy Resources
Abstract: One of the greatest challenges for humanity in the 21st century is to provide adequate energy to allow everyone on the planet to live decent lives, while managing the impact of a rising population and the decline in fossil fuels. In this talk, we will discuss two problems that arise in this context. The first one is faced by electric utilities in the US that use demand response (DR) to handle the supply-demand mismatch. Many DR programs are managed using automated DR devices (ADRs) that, upon receiving a signal from the utility, trigger strategies to reduce the consumption of customers. Most ADRs are one-way communication only; hence, the utility cannot know whether an ADR is reacting to its signal, and is forced to send repairmen periodically. We propose a method that infers the ADR state from meter readings, and uses the estimates to schedule the ADR maintenance near optimally, which results in cost savings of up to 80% with respect to the current practice. The second problem is faced by utilities providing power to isolated communities in sub-Saharan countries. Currently, these utilities use a very simple control. Based on the appliances in their household, customers are assigned individual power limits. In order to protect the micro-grid's power inverter, whenever a household consumption exceeds the assigned power limit, its electricity supply is interrupted. As overall usage can surpass the inverter capacity leading to a shutdown of the entire system, the operator faces a trade-off between revenue and reliability. We propose a robust optimization approach to the problem of dynamically assigning power limits to maximize the utility's revenue. Using the robust control policy can lead to as much as a 100% increase in revenue without sacrificing reliability. This is joint work with Garud Iyengar and Vijay Modi.
Biography: Carlos Abad is a PhD candidate in the Industrial Engineering and Operations Research department at Columbia University. His work is focused on developing computational tools for effectively managing energy resources to achieve two goals: sustainability and reliability. Specifically, he is interested in designing algorithms that allow small residential loads participating in demand management programs to be effectively utilized at the grid level, and methods that allow some of the poorest people in the world to have access to a reliable source of energy at a reasonable price.

Talk Title: Quantum light-matter interfaces based on rare-earthdoped crystals and nano-photonics
Abstract: Quantum light-matter interfaces that reversibly map the quantum state of photons onto the quantum states of atoms, are essential components in the quantum engineering toolbox with applications in quantum communication, computing, and quantum-enabled sensing. In this talk I present our progress towards developing on-chip quantum light-matter interfaces based on nanophotonic resonators fabricated in rare-earthdoped crystals known to exhibit the longest optical and spin coherence times in the solid state. We recently demonstrated coherent control of neodymium (Nd3+) ions coupled to yttrium orthosilicate Y2SiO5 (YSO) photonic crystal nano-beam resonator. The coupling of the Nd3+ 883 nm 4I9/2-4F3/2 transition to the nanoresonator
results in a 40 fold enhancement of the transition rate (Purcell effect), and increased optical absorption (~80%) - adequate for realizing efficient optical quantum memories via cavity impedance matching. Optical coherence times T2 up to 100 μs with low spectral diffusion were measured for ions embedded in
photonic crystals, which are comparable to those observed in unprocessed bulk samples. This indicates that the remarkable coherence properties of REIs are preserved during nanofabrication process. Multi-temporal mode photon storage using stimulated photon echo and atomic frequency comb (AFC) protocols were implemented in these nano-resonators. Our current technology can be readily transferred to Erbium (Er) doped YSO devices, therefore opening the possibility of efficient on-chip optical quantum memory at 1.5 μm telecom wavelength. Integration with superconducting qubits can lead to devices for reversible quantum conversion of optical photons to microwave photons.
Biography: Dr. Andrei Faraon is an Assistant Professor of Applied Physics, Materials Science and Medical Engineering at California Institute of Technology. After earning a B.S. degree in physics with honors in 2004 at California Institute of Technology, he received his M.S. in Electrical Engineering and PhD in Applied Physics both from Stanford University in 2009. At Stanford, Dr. Faraon was involved with seminal experiments on quantum optics
using single indium arsenide quantum dots strongly coupled to photonic crystal cavities in gallium arsenide. After earning his PhD, Dr. Faraon spent three years as a postdoctoral fellow at Hewlett Packard Laboratories. At HP he was involved with pioneering experiments on diamond quantum photonic devices coupled to solid-state spins. He demonstrated the first nano-resonators coupled to single nitrogen vacancy centers in mono-crystalline diamond. Faraon left HP in 2012 to become an Assistant Professor at Caltech. At Caltech, he set up a laboratory specialized in developing nano-photonic technologies for devices that operate close to the fundamental limit of
light-matter interaction. He is focused both on fundamental challenges on how to control the interaction between single atoms and single photons using nano-technologies, and on using nano-photonics to build cutting edge devices for bio-imaging, bio-sensing and photo-voltaic energy harvesting. He is the recipient of the NSF CAREER award and the AFOSR young investigator award.

Talk Title: Light sheet microscopy - a versatile tool for biological imaging
Abstract: Biological research has always dreamed of being able to image every single cell in a live intact multicellular system, quantify the cellular behavior and gene expressions, follow the interactions among cells and between cells and the environment, and use the collected information to build a quantitative and predictive understanding. We will present our efforts toward realizing this dream, utilizing the unique imaging platform of light sheet microscopy, also known as selective plane illumination microscopy (SPIM). As the name implies, SPIM uses a planar sheet of light to illuminate a sample, generating fluorescence over a thin optical section of the sample that is then collected by a wide-field imaging camera oriented orthogonal to the light sheet. We will explain how this simple twist in illumination geometry allows SPIM to have distinct advantages over conventional optical imaging techniques in imaging, at cellular resolution or better, live, fast, and/or large biological samples. We will describe past, current, and future work in our lab in developing and applying this imaging technology, including looking at morphogent gradient dynamics in developing embryos; dynamic motion of developing embryonic hearts; and understanding the synaptic neuroplasticity involved in sleep/wake and learning.
