Summary of Project – POSITION CLOSED

Dr. Shawn Brueshaber (ME-EM) is seeking applications for 1 PhD student interested in researching the fluid dynamics of Uranus’s and Neptune’s atmospheres starting as early as Spring 2024 if the right candidate is found. Uranus and Neptune, the ‘Ice-Giants,’ are the least explored planets of our Solar System yet thought to be one of the most common types of planets in the Galaxy. The National Academies has recently identified Uranus as the highest priority destination for a new “flagship” class spacecraft mission. Atmospheric science will undoubtedly be a major component of such a mission. The atmospheres of the Ice Giants are quite unlike those of Earth and similar ‘terrestrial’ planets (Venus, Mars, and the moon, Titan), and also unlike those of its larger cousins, the Gas-Giants (Jupiter and Saturn). Uranus, and especially Neptune, occasionally form large dark vortices (Fig.1) but what causes them is unknown.

The successful candidate will dive ‘under the hood’ to modify and use the EPIC General Circulation Model (a type of computational fluid code; Dowling et al. 1998) to determine how dark anticyclonic vortices are formed. This NASA funded project seeks to test the hypothesis that deep moist convection (e.g., thunderstorms) is the primary mechanism that forms these enigmatic vortices. An alternative hypothesis is that a non-convective hydrodynamic instability is responsible. Dr. Brueshaber has funding available to support the PhD student for a minimum of three years.

Your Qualifications

• A strong interest in fluid mechanics and meteorology. A strong interest in planetary science is a plus.
• Coursework in fluid mechanics, atmospheric dynamics, or similar. Coursework in computational fluid dynamics (previously, or planned).
• Good programming skills (e.g., Python and/or Matlab, C is a strong plus). Experience with Linux commands are a plus.
• A willingness to learn, modify, and apply a General Circulation Model (GCM).
• Good written and verbal communication skills.
• A Masters of Science in Mechanical Engineering, Atmospheric Science, Physics, or other closely-related field. Graduate standing in any of the above disciplines will be considered.
• Strong oral and written communication skills.
• US Citizenship is NOT a requirement.

Shawn Brueshaber comes to Michigan Tech from Western Michigan University, where he earned his MS and PhD in Mechanical Engineering. He earned his BS in Aerospace Engineering at Embry-Riddle Aeronautical University in Daytona Beach, Florida. After graduating, he spent several years in industry, eventually earning his Master’s degree while working full time. His research at Western focused on the polar atmospheric dynamics of the giant planets—Jupiter, Saturn, Uranus, and Neptune. And that’s just for starters. Welcome, Dr. Brueshaber!

What drew you to Michigan Tech?

I like the climate—cool and snowy.  Seriously, I applied to multiple universities and when I interviewed here, I found it to be a good fit.  

What is your primary area of research and what led you to it?

I’ve always had an interest in weather and planetary science. Once I discovered I could combine them with my formal education of mechanical and aerospace engineering to conduct research, I was off and running!

Can you share a little more about your research and what you like about it?

At first glance, atmospheric planetary science doesn’t seem to hold a lot of everyday, practical problem-solving here on Earth, which is what many engineering students tend to do.  However, because our understanding of weather and climate is a subset of fluid dynamics, and, in turn, is a huge area of physics that is still not fully understood, atmospheric planetary science provides another rich field of science that may eventually lead to a more complete understanding of fluid mechanics. 

My ultimate goal is to develop a comprehensive theory of weather and climate applicable to all planetary bodies with an atmosphere. Perhaps along the way, we will gain a better understanding of turbulence, which can help with generating sustainable fusion power production.

What do you consider an important long-term goal for your research, teaching, or outreach?

I am working towards developing a deeper understanding of how planetary atmospheres work.  I intend to do this by continuing my current research plans, as well as conducting new research focusing on clouds and precipitation in the Keweenaw Peninsula. 

I have some nascent research ideas applicable to biological sciences, too. Through all this, I want to create industry- and graduate school-ready engineers with a love of learning and appreciation for the natural world–and how we can move humanity forward in a more sustainable and compassionate path to the future.

What do you hope to accomplish, as an educator and as a researcher, over the next few years?

I want to set up a more comprehensive suite of meteorology instrumentation for the Keweenaw area, while continuing my current research inquiries on the giant planets. Additionally, I have a strong interest in branching into researching meteorology on Saturn’s giant moon, Titan.  

As for education, I want to develop a new course that teaches engineering students the basics of planetary science, for those that wish to work in the space industry. Understanding why scientists impose a set of instrument requirements for engineers to figure out is an important component in making more efficient and less expensive space exploration missions. In turn, we will get more science return per dollar. 

And, of course, I desire to improve my teaching abilities. I have taught on and off since 1995. I started out by teaching a graduate course (developing a fluids class from scratch), and then undergrad courses (Thermodynamics, Introduction to Mechanical Engineering, and Material Science), and Developmental Algebra. 

Where are you from? What do you like to do in your spare time?

Originally, I’m from Maryland. I like hiking, cross-country skiing, SCUBA diving, backpacking, and running (although I need to start from scratch again). Also reading—history and science fiction—and gaming (both computer and board games).  I enjoy astronomy, cooking, and spending time serving my three cats.

What’s your favorite book, movie, or piece of art?

That is a very difficult question. How can one have only ONE favorite book, movie, or piece of art?  ;-). I’ll answer by saying one of my favorite recently-read books was “Sleepwalkers, How Europe went to War in 1914,” by Christopher Clark.  This book goes into a deep analysis of the situation in Europe and the Near East in the late 19^th century and how Europe’s leaders avoided a number of potential flashpoints into the 20^th century, but infamously and not at all inevitability, stumbling into the catastrophe of World War I, the Great War. This war, perhaps every bit as the Second World War, shapes much of our geopolitics today. 

As for movies, I can’t really single out a favorite.  But I have been very pleased with the recent Star Trek TV series “Strange New Worlds.”  I’m also a big fan of The Expanse, Star Wars, and Battlestar Galactica. If it is science fiction, I’m going to pay attention.   

As for art, the Flammarion engraving is probably my favorite piece. It first intrigued me as a four-year old. I couldn’t stop looking at it and trying to understand it.

In September of 2022, I attended a planetary science conference in Granada, Spain.  I visited the Alhambra complex and fell in love with the architecture of the Nasrid dynasty, and in Cordoba, the Grand Mosque-Cathedral. The use of thin tall columns, arches, color, use of light, water features, and the elaborate application of geometric patterns on tile, and natural, and astronomical themes was breathtaking. 

Any favorite spots on campus, in Houghton, or in the UP?

I’m new to the area so I don’t really have a truly  favorite place yet. However, on previous trips to the UP, I really enjoyed Munising and hope one day to hike part of the long trail above Pictured Rocks. 

Any advice for incoming students?

Learn to organize your day, week, and semester. Establish a healthy and energetic lifestyle, and engage in intellectual interests beyond your major.  I became a huge history buff in college and took several additional history courses as electives. I read many a book on ancient and military history and it has provided me with useful lessons and a sound understanding of how the world really works. If you are an engineering student, simply sticking to engineering courses is a severe detriment, both as a citizen and as an employee. So, find or rejuvenate your intellectual curiosity. Be open to new ideas and new experiences. You get a finite number of orbits around the Sun so make the most of them. 

Associate Professor Bhisham Sharma comes to Michigan Tech from Wichita State University, where he worked as an assistant professor in the Department of Aerospace Engineering. He earned his BS in Mechanical Engineering at the University of Pune in Pune, India, and his MS and PhD in Aeronautical and Astronautical Engineering at Purdue University. He also spent a few years at Purdue as a post-doctoral research associate and a visiting assistant professor. Welcome, Dr. Sharma!

What drew you to Michigan Tech?

I was initially drawn to Michigan Tech for its exceptional academic reputation and its commitment to interdisciplinary research and innovation. This environment offers a fantastic opportunity to foster collaboration, a critical element in addressing complex research challenges. What sets Michigan Tech apart is the visible support and resources provided by the administration, a feature not commonly found at every university.

Another significant factor in my decision was the ME-EM department’s outstanding academic program and its strong emphasis on equipping students with real-world experiences. As a faculty member, my own teaching philosophy and vision perfectly align with the department’s approach as we bridge the gap between theoretical knowledge and practical engineering applications.

Last but not least, who wouldn’t jump at the chance to reside in such a breathtaking and unique natural environment? Michigan’s Upper Peninsula offers a quality of life that is second to none, with an abundance of outdoor activities and natural beauty. I am looking forward to exploring all there is to explore!

What is your primary area of research?

My research primarily falls in the overlap of solid mechanics, structural dynamics, acoustics, and advanced manufacturing. At one end of the spectrum, I seek to understand fundamental mechanics and acoustics of novel engineered material systems such as acoustic metamaterials, phononic structures, architected lattice structures, and stochastic foams. At the other end, I focus on developing advanced manufacturing methods that can enable such structures and to translate this fundamental knowledge—create performance-tailored solutions to critical engineering problems across various industries.

Can you share a little more about your research and what you like about it?

Overall, my research revolves around a central question: Can we develop lightweight structures that possess tailored multifunctional properties for specific applications? Let’s take, for example, the outer casing of a cutting-edge aircraft engine, a nacelle, which is designed as a set of separate components. Each serves a single function: the duct shells bear the primary loads; acoustic liners absorb engine noise; thermal management relies on heat shields; and composite fabric wraps ensure blade containment. This conventional “single-component, single-function” approach hampers cost savings, weight reduction, and fuel efficiency gains. It also constrains innovation in vehicle configuration.

My overarching research objective is to drive a paradigm shift and replace this design approach with a new, “single-component, multiple-functions” approach, a transformation that involves creating application-specific multifunctional structures, and advancing the essential tools for their design, analysis, and certification.

My work is inherently interdisciplinary, encouraging me to delve into physics, mathematics, and manufacturing. This continuous opportunity to acquire new knowledge fuels my passion and excitement for this field. I am motivated by the prospect of pushing the boundaries of what is possible. I find immense fulfillment in the daily process of discovery and learning that this field offers.

What do you like to do in your spare time?

Most of my spare time these days is spent enjoying the adorable shenanigans of my two 1-year old kittens. I love Indian classical music and enjoy discovering new aspects to its underlying theory. I also read quite a bit. I have always been fascinated by geopolitics, so I spend a fair amount of time reading up on the current state of world affairs. I am also an ardent Manchester United soccer fan, and make sure to watch their game over the weekends. Watching TV—baking shows or murder mysteries—is my go-to after a busy day at work.

What’s your favorite book, movie, or piece of art?

Candide by Voltaire and Animal Farm by George Orwell. I have read both books multiple times. Guide, an old Bollywood movie—and Taxi Driver are my favorite movies. My favorite piece of art is Beethoven’s Symphony No. 5. I don’t think any human being has ever created anything more beautiful than its allegro con brio.

Any favorite spots on campus, in Houghton, or in the UP?

I have only been here two months, so it is too early for me to pick a favorite spot! For now, I think the Great Sand Bay in Eagle Harbor is my favorite spot on a warm day.
