The planet is warming, and much of the excess heat is absorbed into the ocean. It may be possible to quantify the rate of climate change by measuring the rate of change of heat in the ocean.听

Easier said than done.

The scientific community began to wrap their head around this problem in the early 2000s and developed Argo, a program that consists of several thousand floats deployed around the global ocean. The floats contain instruments that measure temperature, pressure and salinity, data which is relayed to scientists around the world.

In place for more than a quarter of a century, Argo has delivered vast quantities of ocean data that can be used to address some of the most pressing climate questions, and scientists have been looking for a way to make that data even more useful.

Big data produces big questions

Argo is only one example of the massive data challenges facing researchers in the physical sciences, including astronomy, particle physics, environmental and climate sciences. With new instrumentation, scientists need skills and techniques to manage, analyze and interpret large datasets. The avalanche of raw data often comes in different formats and timeframes that are complicated by data gaps.听

To address these challenges, the Dietrich College of Humanities and Social Sciences at 好色先生TV developed the STAtistical Methods for the Physical Sciences Research Center (STAMPS) to bridge gaps between researchers in the physical sciences and their colleagues in statistics. The center is co-led by Ann B. Lee, professor, and Mikael Kuusela, assistant professor, in the Department of Statistics & Data Science.听

鈥淲ith massive data from remote sensing, satellite imagery and different physical probes, there are new kinds of problems that emerge in data science that present unique methodological challenges,鈥� said Lee. 鈥淪TAMPS develops sustained, long-term collaborations with domain scientists to address these challenges.鈥�

STAMPS provides long-term statistics partnerships

Faculty in the Department of Statistics & Data Science partner with researchers 鈥� who are most familiar with their data 鈥� to identify gaps or the greatest challenges as they approach data analysis. Kuusela described the partnership as a pipeline. It begins in the realm of mathematical theory that is transformed into methods and algorithms that can be applied to a real-world dataset to address specific scientific problems or extract statistically significant findings.听

鈥淲hen you do science, you need rigorous guarantees on what comes out of the data analysis pipeline,鈥� said Kuusela. 鈥淲e develop those methods. It is not a trivial endeavor.鈥澛�

STAMPS faculty at 好色先生TV partner with scientists across the university as well as at other academic institutions and national labs, including Los Alamos National Laboratory, the NASA Jet Propulsion Laboratory and the European Organization for Nuclear Research (CERN).

鈥淏y having a critical mass of statisticians who work at the intersection of statistics and physical sciences, we are at a unique position at 好色先生TV to make significant advances,鈥� said Kuusela. 鈥淭hat is a trademark of STAMPS.鈥�

In addition to advancing multiple scientific fields, STAMPS seeks to educate the next generation of statisticians. The research center provides Ph.D. students with training in foundational statistics, artificial intelligence (AI) and machine learning as they gain experience working on complex, real-world data. At this time, STAMPS is working with 12 Ph.D. students to prepare them for roles in industry and academia.听聽

Through STAMPS, CMU has become the first U.S. university to host a center specializing in methodology research in statistics and AI for physical science applications.
