Uniquely Houston event to convene innovation experts across aerospace, energy, and medicine

guest column

Every year, Houston's legacy industries — energy, medicine, and aerospace — come together to share innovative ideas and collaborate on future opportunities.

For the eighteenth year in a row, the annual Pumps & Pipes event will showcase and explore convergence innovation and common technology themes across Houston’s three major industries. The hosting organization, also called Pumps & Pipes, was established in 2007 in Houston and is dedicated to fostering collaboration amongst the city's three major industries.

With NASA in its backyard, the world’s largest medical center, and a reputation as the “Energy Capital of the World,” Houston is uniquely positioned to lead in cross-industry convergence innovation and is reflected in the theme of this year’s event – Blueprint Houston: Converge and Innovate.

Here's what you can expect to explore at the event, which will take place this year on December 9 at TMC Helix Park. Tickets are available online.

The state of Texas’ aerospace investments

How are the recent strategic investments in aerospace by the State of Texas transforming the space economy and driving growth in adjacent industries? What is the case for cultivating a more dynamic and vibrant aerospace R&D environment?

These are the key questions explored in the opening session of Pumps & Pipes, moderated by David Alexander (Director, Rice Space Institute). Joining the discussion are distinguished leaders Norman Garza, Jr., Executive Director of the Texas Space Commission (TSC); as well as two members of the TSC board of directors: Sarah “Sassie” Duggelby, CEO/Co-Founder of Venus Aerospace; and Kathryn Lueders, GM at Starbase, SpaceX.

This panel will spotlight Texas’ critical role in shaping the future of aerospace, with a focus on its cross-sector impact, from space exploration to innovation in energy and health care. We’ll explore how the state’s investments are fueling research and development, creating economic opportunities, and fostering a more interconnected, high-tech ecosystem for the future.

Real-world applications of robotics and synthetic biology

Explore the groundbreaking intersection of syntheticbiology and robotics as they reshape industries from aerospace to energy to health care. Experts from academia and industry — Rob Ambrose of Texas A&M University, Shankar Nadarajah of ExxonMobil, Shalini Yadav of the Rice Synthetic Biology Institute, and Moji Karimi of Cemvita — will discuss the real-world applications and future possibilities of these two fields, including innovative uses of robotics and drones to monitor emissions from deep-sea oil rigs, and synthetic microbes that convert carbon dioxide into valuable chemical products.

Discover how synthetic biology and robotics are paving the way for a more sustainable, autonomous, efficient, and interconnected future.

The total artificial heart – a uniquely Houston story

Heart failure affects millions globally, yet only a small fraction of patients receive life-saving heart transplants. The Total Artificial Heart (TAH), developed by BiVACOR, offers a revolutionary solution for patients with severe heart failure who are ineligible for a transplant.

Luminary leader, Dr. Billy Cohn, will discuss the groundbreaking BiVACOR TAH, a device that fully replaces the function of the heart using a magnetically levitated rotary pump. This innovative approach is part of an FDA-approved first-in-human study, aiming to evaluate its use as a bridge-to-transplant for patients awaiting heart transplants.

Moderated by Dr. Alan Lumsden (Chair Dept. of CV Surgery at Houston Methodist Hospital), join Dr. Cohn as he shares insights, and the story-behind, this pioneering technology and its potential to reshape the future of heart failure treatment, offering new hope to thousands of patients in need.
