Joe previously served as President and CEO for Callon Petroleum Company (“Callon”), which completed its sale to APA Corporation on April 1, 2024 for an enterprise valuation of approximately $4.5 billion. He joined Callon in April 2012 and led the transformation of the company from a Gulf of Mexico-focused entity into an onshore unconventional operator in his capacities as CFO and CEO during his tenure. Prior to joining the Callon management team and ultimately serving on the Board of Directors, Joe had a long-standing relationship with Callon in his positions as a Managing Director with the energy investment banking groups of Merrill Lynch & Co. and Barclays Capital Inc. until 2009. In addition to his extensive work with upstream oil and gas clients, he was involved with mergers & acquisitions and capital raising transactions for clients across the entire energy value chain during his investment banking career that began in 1992. In February 2009, Joe founded MarchWire Capital, LLC, a financial advisory and strategic consulting firm, and subsequently served as Head of Structuring and Execution with Merrill Lynch Commodities, Inc. from January 2010 until November 2011, overseeing a portfolio of physical natural gas capacity positions and originating structured transactions with oil and gas, LNG and power companies.

Joe graduated with a Bachelor of Science degree with distinction from Cornell University and received his MBA with distinction from The Wharton School of the University of Pennsylvania.

Alexis Battle is a Professor of Biomedical Engineering at Johns Hopkins University, with courtesy appointments in Computer Science and Genetic Medicine. She is the Director of the Malone Center for Engineering in Healthcare and the Interim Co-Director of the Data Science and AI Institute at JHU.  She specializes in unlocking secrets of the human genome by analyzing large-scale genomic sequencing data to understand the impact of genetic variation on the human body.  Battle’s research is concentrated on the development of computational biology tools and machine-learning strategies to examine genetic differences on gene regulation and disease. A leading member of the National Institutes of Health’s (NIH) Genotype-Tissue Expression (GTEx) Consortium, she focuses on predicting the effects of variation in noncoding DNA sequences.  Findings of her work on a GTEx project, which studied how genetic patterns lead to molecular changes within specific tissues, were published in 2017 in the journal Nature.

At JHU’s “Battle Lab” her research also includes development of new methods to evaluate and predict the impact of personal genomics, and rare genetic variants that may significantly impact an individual’s health.  These methods are helping to improve understanding of how genes work together and how their interconnected pathways may influence complex traits.  Additionally, Battle is involved in a host of ongoing research initiatives, from building integrative networks for genomic analysis of autism, supported by NIH, to predicting rare Mendelian disease variants using genomic data, funded by her Searle award and 2017 JHU Catalyst Award.  She is also the recipient of a 2019 Johns Hopkins Discovery Award for studying the genetics of atherosclerotic cardiovascular disease.

Alexis has received numerous awards, including the 2022 JHU President’s Frontier Award, and was named a 2016 Searle Scholar and a 2020 Microsoft Investigator Fellow. Her research group uses machine learning to analyze large-scale genomic and health data to understand how genetic variation affects the human body. She earned her Ph.D. in Computer Science from Stanford University in 2013, after receiving her Bachelor’s degree in Symbolic Systems from Stanford in 2003. Alexis also spent several years in industry as a manager and member of the technical staff at Google, Inc.

In 20 years of U.S. government service with a final tour at the White House in the Office of Science and Technology Policy, where she developed national policy to facilitate the multibillion-dollar space economy. Dr. Uzo-Okoro’s career includes contributions to national policy and over 60 NASA missions and programs. Her experience creating complex spacecraft, guided by values of efficiency, sustainability, and global collaboration, resulted in strategies for U.S. technological leadership and future economic growth. Dr. Uzo-Okoro is a Venture Partner at SineWave Ventures, a Senior Fellow at Harvard University, and an advisor to aerospace and defense companies.

Dr. Uzo-Okoro drove innovation in space, aeronautics, and advanced manufacturing at the White House Office. She developed national policy to facilitate the multibillion-dollar space economy. Her policy work included action plans in the areas of monitoring our climate and Earth through satellite observations, ensuring Space Sustainability through national and G7 action on Orbital Debris, and securing U.S. preeminence in Low Earth Orbit. She also worked to prepare our critical infrastructure for the impacts of Space Weather, and outlined national priorities for the aviation industry. She created supply chain tools to accelerate resilient solutions in several manufacturing sectors to benefit global businesses, end-consumers, and society. She also worked to grow the space asset class. She expanded the existing field of on-orbit space services and ushered in a strategic vision and action plan for the United States to lead in universal innovative capabilities, such as, robotic assembly and refueling satellites in space.

In 17 years at NASA, she contributed to over 60 missions and programs – as an engineer, technical expert, manager, and executive – in earth observations, planetary science, heliophysics, astrophysics, human exploration, and space communications, which represent $9.2B in total program value. She served as the technical authority on over 20 operational missions. Within research and development, she led the development of remote-sensing image registration algorithms, which resulted in NASA-owned registration algorithm patents.

She earned an undergraduate degree in Computer Science from Rensselaer Polytechnic Institute,and masters degrees in Aerospace Systems, Space Robotics, and Science & Technology Policy from Johns Hopkins University, MIT, and Harvard University, respectively. She also earned a doctorate degree in Aeronautics and Astronautics from MIT. She received several NASA awards and the 2023 Commercial Space Federation Commercial Space Policy award.
