The road that makes up a career, especially one related to academics and research, is built one brick at a time.

Those individual bricks come from every opportunity someone takes, said听Rebecca Nugent, the Stephen E. and Joyce Fienberg Professor of Statistics & Data Science at 好色先生TV.

鈥淎ll the major advances that come with people making huge leaps in their careers, they all started with putting down little bricks, one at a time,鈥� she said. 鈥淓ventually, those bricks become something really big.鈥�

No matter the discipline, mentorship and outreach are important to encourage scaffolding opportunities that might start with agreeing to meet for coffee, turning in an application or asking for feedback.

鈥淚鈥檓 a big believer in building roads brick by brick,鈥� she said. 鈥淚 have been the beneficiary of many people believing that I could take that next step, and I think that approach is crucial for us developing the next generation of scientists and educators.鈥�

Just one in three scientists worldwide is a woman, according to a听.听At Carnegie Mellon, women in the sciences contribute to advancement and innovations at the forefront of discovery, while lifting each other along the way.

Sydney Prescott

When she was in high school, Sydney Prescott found out about the听Department of Chemistry鈥檚 annual student-produced murder-mystery musical dinner.

鈥淭his program showed that people cared so much that they were willing to do something so elaborate for fun,鈥� she said. 鈥淚 realized this would be a good place for me.鈥�

Now a senior majoring in听chemistry听补苍诲听environmental & sustainability studies, Prescott has been working with about 15 other students to produce this year鈥檚 dinner, which is themed to the musical 鈥淐hicago,鈥� set for March 19.

The production, a听CMU tradition for almost 20 years, provides a bonding experience for those involved and a way for them to share their skills outside of the classroom.

鈥淚鈥檝e really enjoyed working on different teams, no matter what the activity or opportunity has been,鈥� she said. 鈥淔or something like the murder-mystery dinner, I鈥檝e seen how everyone has to come together and figure out each other鈥檚 strengths to work toward the end goal of the final performance.鈥�

Prescott has worked for three years as an undergraduate researcher in the lab of Chemistry Professor听Stefan Bernhard. Prescott synthesizes iridium-centered complexes and tests their luminescent properties and their potential applications in renewable energy systems.

鈥淚鈥檝e had to adjust the synthetic method to improve the yield and purity,鈥� she said. 鈥淚t鈥檚 been a lot of work on the bench, doing chemistry.鈥�

She credits听Karen Stump, teaching professor and director of undergraduate programs in the Department of Chemistry, with helping her find opportunities. Aided by chemistry doctoral student Mitch Baumer, she learned how to contribute to the lab鈥檚 research and completed a project funded by the听Summer Undergraduate Research Fellowship.鈥ㄢ�≒rescott has applied to doctoral programs to study inorganic chemistry and renewable energy.

鈥淚 feel a lot more prepared for the next step. I want to be able to have leadership over the experiments I鈥檓 running,鈥� she said. 鈥淲hatever my future goal is, I want to have a really solid understanding of research and be able to make informed decisions about what direction the project goes in.鈥�

With the听, Prescott has helped plan activities such as partnering with a local Pittsburgh Girl Scout troop to teach a science badge. She served as president of the student group last year and as vice president the year before.

鈥淟eading that group has helped me meet other women in science and organize outreach activities in the community,鈥� she said. 鈥淚 definitely didn鈥檛 know any college students in science when I was little, so we give them the experience of getting to see what students at Carnegie Mellon are really like."

She served as a residential assistant her first two years and now, as a community adviser, oversees a team of RAs.

With her involvement in student life, Prescott said she has learned how working together toward a goal 鈥斕齱hether a project or a science-infused musical 鈥� helps build connections with other students more easily that can grow in to an authentic network in the future.

鈥淓ven casual social events make it easier to meet people, then you have a support system that helps you succeed,鈥� she said.

In high school in Victor, New York, she liked to keep busy with extracurricular activities, including earning her Girl Scout Gold Award, which combines leadership and community service.听鈥ㄢ�–ontinuing to take part in community-building during her college career at Carnegie Mellon felt like a natural progression.

鈥淚鈥檓 a big believer that the more effort you put into an experience, the more you鈥檒l get out of it,鈥� Prescott said.

Valentina Dutta

The construction of the Large Hadron Collider (LHC), the particle accelerator at the European Organization for Nuclear Research, known as CERN, in Switzerland, captured the interest of听Valentina Dutta when she was a teenager in India. She read a story about its construction in the science section of her local newspaper.

鈥淚 found it really fascinating, you know, with this big collaboration that was composed of scientists from all around the world working together to build something, to discover something fundamentally new about the universe,鈥� said Dutta, now an assistant professor in the听Department of Physics听within CMU鈥檚听Mellon College of Science.

As an undergraduate researcher, she worked at Fermilab near Chicago on another particle accelerator, the Tevatron, which similarly uses electromagnetic fields to propel charged particles at very high speeds and measure the energy and reactions when they smash together.

Years later, Dutta, as a doctoral student, worked in Switzerland on the Compact Muon Solenoid (CMS) experiment at the LHC. She was in the room when the discovery of the Higgs boson particle was announced to the world in 2012.

鈥淭he article I鈥檇 read when I was young had talked about this quest to discover the Higgs boson, which was the last missing piece of the standard model of particle physics,鈥� Dutta said. 鈥淚 was so fortunate as to actually end up working on that.鈥�

A breakthrough in scientific understanding of the structure of the universe and how particles acquire mass, the subatomic particle relates to Dutta鈥檚 work today.

鈥淵ou look for the particles you know it decays into and try to match it up with what you expect for the Higgs itself,鈥� she said. 鈥淚 was looking for evidence of its decays into a particular type of particle called the tau lepton.鈥濃�ㄢ�∟ow, as part of a major collaboration across the world, Dutta and other Carnegie Mellon faculty members are听leading an effort here to build and test modules听that will be used in the study of particle physics.

In the ongoing CMS experiment, detectors capture 3D images of the particles鈥� impacts at the rate of one every 25 nanoseconds, or 40 million images a second.

Dutta, along with Professor听Manfred Paulini and Associate Professor听John Alison, are leading a team building 20-centimeter hexagonal electronics modules at Carnegie Mellon's module assembly center for a High-Granularity Calorimeter upgrade to the CMS detectors. The upgrade will enhance the quality of the recorded data as well as cope with large amounts of ionizing radiation.

Over the next three years, the teams at Carnegie Mellon hope to build 5,000 modules.

鈥淲e鈥檙e in the pre-production phase now and will be producing up to 12 modules per day in a few months鈥� time,鈥� Dutta said.

Looking back, Dutta remembers the importance her undergraduate research mentor, the late Meenakshi Narain at Boston University, had on her, and she keeps mentorship at top of mind when working on such a large-scale, worldwide collaboration.

鈥淚鈥檝e definitely been fortunate to find mentors along the way who helped me gain perspective as role models,鈥� Dutta said. 鈥淚 try to pass that on in my relationships with students and collaborators because mentorship is hugely important.鈥�

Coty Gonzalez

As a research professor at the听Department of Social and Decision Sciences, Cleotilde (Coty) Gonzalez examines how humans make choices in dynamic environments.听

Then, those thought processes are used to create and train computer models.

Once the computer models are perfected, they can, in turn, be used to help humans make even better decisions.

鈥淥ur main tool for doing that is a computational cognitive model,鈥� she said. 鈥淭hese computer programs emulate human cognitive processes from perception to action. Then we can use that tool, that computational model, to help humans make better choices.鈥�

Gonzalez founded the听Dynamic Decision Making Laboratory听in 2002, after joining the faculty at Carnegie Mellon in 2000.

鈥淢y interest in decision-making came from very early on, but was more about the computer, not so much about the human,鈥� she said. 鈥淏ut during my Ph.D., I realized there needs to be a cohesion between the human and the computer for decisions to be made properly.鈥�

She has been principal or co-investigator on a wide range of multimillion and multiyear collaborative efforts with government and industry, including NSF AI National Institutes, Multi-University Research Initiative grants from the Army Research Laboratories and Army Research Office; large collaborative projects with the Defense Advanced Research Projects Agency (DARPA) and the Intelligence Advanced Research Projects Activity (IARPA).

As research co-director of the听National AI Institute for Societal Decision Making, Gonzalez helps lead a $20-million, five-year program that examines interdisciplinary solutions to aid in disaster management and public health.

When a disaster happens, which is usually sudden and evolves in a nonlinear way, researchers are studying human reactions that can better allocate resources.

Creating tools for future research using data from human decisions also fuels the institute鈥檚 work, Gonzalez said.

鈥淚鈥檓 looking forward to advancing our work on AI,鈥� she said. 鈥淭here are so many ways to bring my cognitive models and demonstrate the benefit for AI and machine learning in particular.鈥�

The team, including four undergraduate students from different departments, is developing a prototype game that uses the data as part of one of those tools for disaster managers.

Data will inform and be synthesized into a large-language model, which the manager could use to decide where to send resources and of what types.

鈥淚 believe in the human ability to adapt to dynamic tasks. That is indeed a trademark of the kind of work we do,鈥� Gonzalez said. 鈥淲e study learning and adaptation, so how do humans build adaptation? We build it through a diversity of knowledge, experiences and cultural backgrounds.鈥�

Using instance-based learning theory, which she developed along with other researchers in 2003, models for cybersecurity, network science and human-machine teaming have emerged.

鈥淯sually, decision-making is studied by assuming people evaluate all their possible options and weigh the pros and cons,鈥� she said. 鈥淗owever, most people actually use their experience or someone else鈥檚 experience to make decisions.鈥�

The theory has evolved, but the complexity and basic building blocks of human memory that we use for decision-making are the same, she said.

鈥淚 still believe the way to address challenges the real-world presents to us is to study complex tasks, not simplistic ones,鈥� she said.

During her more than 20 years leading the lab, she has mentored 36 postdoctoral researchers 鈥� and most have added a pin to a world map in the SDS office.

鈥淚t鈥檚 important to me that they are productive and feel motivated,鈥� she said. 鈥淪ome of them might think I鈥檓 pretty tough, but I want them to be productive, while recognizing their abilities and interests.鈥�

Rebecca Nugent

When Rebecca Nugent began her career in academia, she considered how to teach college students about data, but now more than ever, she believes the everyday person should also know more about data and how it affects them.

鈥淚f we don't empower people to learn about data and to use data to make informed decisions in their own lives, then it's a huge missed opportunity for us,鈥� she said.

Nugent serves as the department head for the听Carnegie Mellon Statistics & Data Science Department听in the听Dietrich College of Humanities & Social Sciences.

Her current research focus is the development and deployment of low-barrier data analysis platforms that allow for adaptive instruction and the study of data science as a science.

With an increased amount and access to data, especially thanks to artificial intelligence, the foundational framework for interactions with technology is changing.

鈥淗ow do we be responsible about this?鈥� she asked. 鈥淗ow do we use AI and data science to help people?鈥�

Statistical principles such as randomness, uncertainty and what it means to be a prediction versus a fact should be a part of any future data literacy programs, apps or projects, Nugent said.

鈥淲hat can we do with developing technology to provide more personalized support or personalized treatment to help people make decisions about their own health care journey,鈥� she said. 鈥淚magine if that information is wrong, or imagine if they don鈥檛 know how to interpret the information that they鈥檙e getting.鈥�

As she serves as education and outreach lead for the听National AI Institute for Societal Decision Making听(as part of the leadership team with Gonzalez), she keeps these principles in mind as well.

鈥淚f people are uncomfortable with data-centric technology and nobody understands what its purpose is, how can it help?鈥� she said.

She also is a part of the听Carnegie Mellon Sports Analytics Center听that uses sports data as an entry point to encourage interest in how to better understand data, and works with the听. Funded by the National Science Foundation, the national network is dedicated to creating and sharing Sports Content for Outreach, Research and Education in statistics and data science.

鈥淲e're creating modules that explain data science and statistics content to people who are newer to these fields, but we do it with sports analytics,鈥� Nugent said.

Data and artificial intelligence isn鈥檛 meant for a vacuum. It鈥檚 meant for people.

鈥淧eople are central to everything that we're doing,鈥� Nugent said. 鈥淎nything that we're designing and building, we're doing with the idea that it's either going to be used by a person, or it's going to help support someone.鈥�

With every research project and collaboration that she works on, Nugent said she prioritizes mentorship and advocacy.

鈥淭hose aren鈥檛 the same thing,鈥� she said. 鈥淢entorship is important for answering people鈥檚 questions, making sure they have information, then providing them with support to move forward. Advocacy is providing opportunities for talented people to grow and rise to the occasion.鈥�
