Topic: Disaster Decision Making: Integrated Prediction and Optimization for Resilience Planning
October 15, 2021 at 10:00 am (CDT)
How come we still have devastating weather-related tragedies despite increasingly powerful weather prediction tools? Could it be as simple as “connecting the dots?”
The 10-day power outage following Hurricane Ida in New Orleans resulted in heat-related deaths. Uri, the February ’21 winter storm, caused a power outage that resulted in deaths in Texas due to lack of heating in freezing temperatures. It is disappointing that we have high-resolution weather prediction models, yet we still struggle to prevent these disasters. One potential culprit is the disconnect between prediction models and disaster decision making. Our research bridges this gap by linking them. When integrated and optimized, our models suggest resilience decisions based on a full grasp of the uncertainty quantified using the scenarios created with the most up-to-date predictions at hand. Our approach captures the infrastructure network interactions and correlations of potential impacts of the disaster, and explicitly models the dependency between three stages of resilience decision making (mitigation, preparedness and recovery), resulting in well-informed decision all around. We present results from multiple projects using two infrastructures, the healthcare network and the power grid, impacted by two types of events, hurricanes and winter storms (using Harvey and Uri as examples), all tested on realistic Texas-based datasets.
Erhan Kutanoglu specializes in integrated humanitarian logistics and disaster analytics, particularly hurricane and other extreme weather event mitigation, preparedness and recovery decision making and optimization. His goal is to combine predictive science-based models with prescriptive stochastic optimization models to develop an end-to-end understanding of uncertainty and optimized decision making in humanitarian logistics and disaster resilience, particularly for critical infrastructure such as healthcare and power grid. His other interests span manufacturing and service logistics optimization, including supply chain and network design, inventory management, transportation and production planning and scheduling. He holds a PhD in Industrial Engineering from Lehigh University, and is a recipient of NSF CAREER Award and IBM Faculty Award.
Dr. Moriba Jah
Topic: Monitoring the Nature & Behaviors of Anthropogenic Space Objects
September 24, 2021 at 10:00 am (CDT)
We currently track over 26000 unique anthropogenic space objects orbiting the earth. Of these, roughly 4000 are satellites that provide services or capabilities of use and the remainder is garbage. There is a growing number of space actors, all driven to make use of outer space as they desire without a mechanism for global governance or joint resource utilization. This, inter alia, is leading to a certain tragedy of the Commons, unless a method of aggregating massive amounts of disparate and heterogeneous data can be developed and made to serve the various needs of space safety, security, and sustainability. In order to support a variety of decisions, there is a foundation need to quantify, monitor, and assess the nature and behaviors of the objects in this near-earth space ecosystem. This work will describe these efforts and provide examples of our state-of-the-art in this endeavor.

Topic: Next Generation Imaging in Science and Medicine
April 30, 2021 at 10:00 am (CDT)
Past decades have seen dramatic developments in optical imaging technologies, computing power, and data accessibility. These developments have recently combined to spawn the field of computational imaging, where optical systems and computational algorithms are jointly designed within data-driven imaging pipelines. This new imaging paradigm has found great success in consumer photography, where mobile phones routinely offer low-cost and high-resolution imaging with noise reduction, 3D imaging, digital refocus, etc. New research brings a similar paradigm shift into optical microscopy, and specifically explores big-data computational microscopy techniques for the biomedical and clinical sciences.
The unique challenges associated with wavelength-scale scientific imaging distinguish microscopy from photography and make it an exciting application for cutting-edge computational research. This talk will focus on recent developments in computational microscopy that enable multi-dimensional super-resolution as well as 3D imaging into optically scattering biological specimens, with a goal to drive scientific and medical discovery. Innovations from this work can be applied broadly across several basic-science, biomedical, and clinical fields, such as pathology, developmental biology, cancer-biology, immunology, physiology, and neuroscience.
Shwetadwip Chowdhury is an Assistant Professor in the Department of Electrical and Computer Engineering at the University of Texas at Austin. His research interests are in developing next generation optical imaging technologies for applications in science and medicine. A key emphasis in his work is the joint design of novel optical imaging systems and advanced computational frameworks. This co-design of hardware and software enables imaging capabilities not possible in traditional optical imaging systems. Dr. Chowdhury’s work on deep tissue imaging is currently funded by the Chan Zuckerberg Initiative, and he was recently named a 2021 Fellow for the new Scialog initiative, Advancing Bioimaging.

Dr. Joan Brennecke
Topic: CO2 Capture with Ionic Liquids
March 26, 2021 at 12:00 pm (CDT)
Carbon dioxide (CO2) is a potent greenhouse gas (GHG) and contributions of CO2 emissions to climate change is one of our most pressing environmental challenges. Separation of CO2 from stationary emission sources, such as power plants and chemical manufacturing facilities, followed by geological sequestration and/or conversion to useful products, will likely play a crucial role in GHG mitigation. Current technology using absorption with aqueous amine solutions is energy intensive and suffers from corrosion, degradation and other challenges. Our research has focused on developing a new class of materials, Ionic liquids (ILs), for CO2 capture applications. Ionic liquids are salts with low melting points so that they are liquid in their pure state (i.e., without any water) even at room temperature. Since they are salts, they have exceedingly low vapor pressures, so they will not evaporate into the cleaned gas stream from which CO2 has been removed. They can be made from innumerable different cations and anions along with a wide variety of substituents. Thus, they can be designed and tuned for specific CO2 separation applications. In this talk, we will present our major developments in designing, synthesizing, and testing ILs for CO2 separations.

Topic: Unlock Energy at Sea - Design of Offshore Platforms for Oil, Gas and Wind
March 12, 2021 at 10:00 am (CDT)
For more than 100 years, people have endeavored to unlock hydrocarbon resources beneath the sea. In the earliest days, clever engineers used long piers jutting out into the ocean and lakes. Today, energy is harvested from coastal locations to hundreds of miles from shore in water depths up to 3,000 meters, using fixed and floating offshore platforms. The evolution of technology and innovation in the design of fixed and floating offshore platforms has been integral to the success of the offshore energy industry. This talk will focus on the history of offshore structures and an introduction to the wide range of structural types and the skills needed to design, build and install them. For further learning, the University of Texas at Austin Cockrell School of Engineering Executive Learning program offers three short courses on offshore platform design, as well as a new Fundamentals of Offshore Engineering Professional Certificate.

Dr. Manish Kumar
Topic: Bioinspired Ideas for Sustainable Separations
January 29, 2021 at 10:00 am (CDT)
Membranes are rapidly becoming the fastest growing platform for many process applications in water treatment, process industries, pharmaceutical manufacturing and food processing. This talk will present ideas for bioinspired separations that could enable difficult separations while reducing the impact on the environment by reducing energy input, both embedded and operational. All synthetic membranes (and indeed most separation processes) have selectivity-permeability tradeoffs, i.e. if a membrane has high permeability, it will have a lower selectivity between two solutes or between a solute and a solvent. In molecular separation dense membranes, separation is due to the mechanism of solution-diffusion through a wide distribution of free volume elements which is responsible for the trade-off. A simple solution, in concept, to such a challenge is to do what nature does – design precise angstrom to micron scale pores or free volume elements with no polydispersity. We will discuss bioinspired ideas, and its realization in our lab, and possible applications of such an ideal membrane based on biological protein channels and artificial channels that mimic their structure. We will also describe an ongoing project in our lab to create interfacially polymerized channel-based membranes for highly selective gas separations and other applications.
Manish Kumar is an Associate Professor of Environmental Engineering at UT Austin. He received his bachelor's from the National Institute of Technology in Trichy, India in Chemical Engineering.

Topic: When will the price of oil return to pre-pandemic rates?
November 20 at 10:00 am (CDT)
In 2020, the human population and its behavior has been unexpectedly altered by the COVID 19 Pandemic. Everyone has been affected to some degree…some of the affects were positive but most were not positive. The changes in behavior of the population have altered the behavior of the world economies. The supply and demand systems of these economies have adjusted to meet pandemic needs for goods and services.
One noteworthy and severely affected economic subsystem is the worldwide demand for energy, in general and motor fuels, specifically. The actions taken by governments located around the world to control the spread of COVID caused a sudden and dramatic reduction in the demand for motor fuels and for crude oil, the raw materials used to make most of those fuels. The reduction in consumer demand rocked the system and backed up the fuel supply chain from the refineries to the wellhead.
Since February 2020, the Upstream, Midstream and Downstream business units involved in providing fuels to industrial, commercial and transportation end users worldwide scrambled to adjust to the reduced demand. Cuts were made across the system. Now, all parties are trying to feel the bottom in demand and at the same time, predict the path to pre-pandemic consumption of fuels.
Rick Bobigian has been teaching the Macroeconomics of the Upstream Oil & Gas Business since 1986, as a module for Petroleum Fundamentals, a core course of PETEX. He created this module for the course to address the last major slump in demand for fuels. In this event, he will offer a view of the future for fuels built on the fundamentals. As in all prognostication there are two parts; that is, the prediction itself and the timing of the prediction. Come see what he has to say.
Rick Bobigian is the President of 1776 Energy located in Houston, Texas. He has been an Instructor for PETEX since 1977. He is a graduate of the Colorado School of Mines with a BSc. in Geologic Engineering.
Dr. Peter Stone

Dr. Ofodike Ezekoye
Topic: Understanding Safety for Lithium ion Batteries
September 25th at 10:00 am (CDT)
For most new technologies the drivers for adoption are based on factors like image enhancement, cost, perceived usefulness, usability, and aesthetics. Safety is rarely considered in early production adoption and is, thus, less emphasized in early design and development of new technologies. Designing for safe use and operation is challenging because prior to market penetration it is difficult to imagine all the failure modes that may occur with any given new technology. Safe design and use of lithium-ion battery operated systems have faced some of these challenges.
In this seminar, Dr. Ezekoye will discuss case studies of battery system failures, failure mechanisms of lithium-ion battery systems, and research approaches to understand the failure cascade and improve safe design of battery systems.
Dr. Eric Bickel
Topic: COVID-19 – What is the data telling us?
August 28th at 10:00 am (CDT)
During this discussion, Eric Bickel will analyze the performance of the models used to forecast the spread of COVID-19 and relate differences in performance to differing modeling approaches and structures. For example, some COVID-19 models are “bottom-up” and model the interactions between individuals and communities in detail (i.e., SIR models). While other models are “top-down” and attempt to capture the high-level dynamics of the spread. We will also be comparing the performance of these models to a simple (two-equation) model that we have used to forecast the spread of COVID-19 at the national, state, and local level. Bickel will finish this discussion by talking about apparent paradoxes present and the implications for decision analysis.
Dr. Venkat Subramanian

Topic: Project Astra and methane emissions in upstream oil and gas
Presented on: June 26th, 2020
This first-of-its-kind project aims to allow producers to find & fix significant methane releases at or below the cost of current monitoring. Project ASTRA, will establish a sensor network that will leverage advances in methane-sensing technologies, data sharing and data analytics to provide near continuous monitoring. This will allow producers to find and fix significant methane releases at or below the cost of current monitoring technologies, most of which measure emissions only on an annual or semi-annual basis.
