Read through this menu of field descriptions and click on the names of people whose jobs sound interesting. These people are STEM professionals: scientists, computer technologists, engineers, and mathematicians.  They ask huge and tiny questions, helping us better understand how the world around us works. They build everything, from transportation systems that help people move around their communities and farther away to tiny devices that kill cancer cells. And they need people like you to learn all of the math (and science!) you can, read and explore the world around you in person, and head off to college and beyond to train to be the scientists, technologists, engineers, and mathematicians (STEM professionals) of the future.

Applied mathematics involves using math to solve problems in the “real world.” An applied mathematician might answer questions raised by physicists, chemists, engineers, environmental scientists, or other people trying to understand or build things. Fern Hunt, an applied mathematician, studies “phenomena that you might observe either with numbers or in nature or in everyday life which seem unpredictable.” She asks questions about probability, dynamical systems, and chaos theory in her work at the National Institute of Standards and Technology.  Applied Mathematician Erika Camacho builds mathematical models that help scientists understand how our eyes work. The math she does helps them develop better treatments for the genetic disease called retinitis pigmentosa. When working at Los Alamos National Laboratory, she helped the U.S. government analyze ways of limiting the growth of terrorist groups. Steven Strogatz investigates the ways math shapes biological rhythms in creatures from fireflies to human beings.  Computer Scientist Bernard Chazelle, also an applied mathematician, studies the natural algorithms behind the behavior of flocks of birds, swarms of insects, and other large groups which appear to have a mind of their own.

Arithmetic Geometer

Jordan Ellenberg

 

Arithmetic geometers, like mathematician Jordan Ellenberg, explore the ways number theory and geometry overlap.  For instance:  the number of solutions to an equation in whole numbers is related in a still-mysterious way to the shape of the region described by the equation’s solution set in real and complex numbers!

Atmospheric Chemist

Atmospheric chemists like this Energy Economist study the chemistry of Earth’s atmosphere, the gases that surround our planet. While in graduate school at the Massachusetts Institute of Technology, he studied fluid dynamics and chemical modeling, looking at the ways aerosols (tiny particles in air and mist) produced by human industry as well as natural processes affect clouds.

Where do animals live? How long do they live? How many offspring (babies) do they produce? How far do they travel? How do they communicate? These are the sorts of questions that behavioral ecologists like John Hoogland ask about the animals they study. Zoologist Hoogland studies prairie dogs: he watches them from a tower every day, for five months of every year.  His colleague, Charles Brown, analyzes the colonies cliff swallows live in and the ways their behavior and morphology (e.g. their wings, tails, legs, and bills) change in response to their environment. And Behavioral Ecologist Jeanne Altmann studies the family relationships of baboons in Kenya’s Amboseli National Park. Biological Anthropologist Erin Vogel studies the behavior of orangutans to help us understand how early humans adapted to changes in their environment. She examines the relationships between the food they eat and their energy levels and general health.

Eugene Desombre
Luke Moe

 

 

 

 

 

Biochemists study chemical processes which occur within living organisms. They explore the chemistry of biology: the molecules in plants and animals and the ways they behave. Microbiologist Luke Moe, who did his doctorate in biochemistry at the University of Wisconsin, studies the ways enzymes within tiny creatures interact with chemicals. Chemist and Cancer Researcher Eugene DeSombre’s research explored the role the hormone estrogen plays in breast cancer and identified ways to figure out which cancers would respond to estrogen-related treatments.

Bioengineer

Derek West

 

Bioengineers, biological engineers, and biomedical engineers use biology, physics, chemistry, math, and computer science as well as the principles of engineering to solve medical and other biological problems.  Bioengineer and Interventional Radiologist Derek West uses tiny particles of gold to cure people (and mice!) who have cancer.

Biological Anthropologist

Erin Vogel

Anthropologists study the human species, using archeology and other tools to understand human beings and our evolution. Studying other species of primates helps scientists learn about us as well as our closest animal relatives. Behavioral Ecologist Erin Vogel tracks, observes, and analyzes the health of Borneo’s orangutans.

Biologists study life, from animals to plants to tiny organisms you can’t see without a microscope. Environmental Microbiologist Luke Moe works with microbes living in the soil around the roots of plants and looks at the ways tiny creatures break down chemicals.

Behavioral Ecologist Charles Brown studies cliff swallows. He gathers data on how the colonies they live in, their behavior, and their average size change with their environment.

Biostatistician

Andrew Vickers

 

According to Cancer Researcher Andrew Vickers, statistics involves “turning data into knowledge.” Statisticians use math to help them gather, understand, and explain data (huge groups of numbers) about all sorts of different topics, from how well a soccer team or a baseball player did last season to how well a surgeon helps patients recover from an illness.  The “bio” in biostatistics refers to life.  Biostatisticians like Andrew Vickers work with data related to living beings.

Cancer Researcher

Millions of people come down with cancer each year, inspiring scientists to try to figure out how to prevent, diagnose, treat, and cure the different forms of this disease.  Biostatistician Andrew Vickers helps doctors improve the ways they identify and treat prostate cancer. Bioengineer and Interventional Radiologist Derek West uses nanotechnology to kill cancer cells. Biochemist Eugene DeSombre, whose PhD is in chemistry, discovered how different breast cancers react to estrogen and developed a test for that, helping doctors figure out how to treat different cancer patients.

Carnivore Ecologist

Rae Wynn-Grant

Carnivore ecologists study carnivores, animals which eat other animals.  Ecologists help us learn about nature by researching animal and plant species and the ways they affect each other and are affected by their environment. Conservation Biologist Rae Wynn-Grant has studied African lions and the black bears of the Lake Tahoe Basin.

Chemist

Eugene Desombre

Chemists are architects on a tiny scale. They design and build molecules, structures composed of just a few atoms. By precisely combining chemicals and sometimes using catalysts, molecules that help a chemical reaction happen more quickly, chemists create materials suited to all sorts of different uses, from gasoline to carbon fiber to lifesaving medicines. They also investigate the molecular structure of different types of already-existing matter.  Biochemist and Cancer Researcher Eugene DeSombre discovered how different breast cancers react to estrogen and developed a test for that, helping doctors figure out how to treat different cancer patients.

Civil Engineer

Cynthia Clark
Tysheina Robertson
Laura Gooch

Civil Engineers design, build, and help maintain public works (structures like bridges, dams, and buildings created for communities by the government).  They create and improve systems to make sure modern societies have drinking water, reliable transportation, a clean environment, and energy. Civil and Water Resource Engineer Cynthia Clark helps design and maintain systems to distribute water among the people of Idaho. Civil Engineer Tysheina Robertson is helping build Denver’s first commuter rail. When Ornithologist Laura Gooch worked as a Civil Engineer, she helped provide Texans with the water they needed and helped clean up toxic waste in Ohio. And Civil Engineer Rachel Davidson studies ways to improve systems that help protect people from natural disasters like hurricanes and earthquakes.

Computer Scientist

Bernard Chazelle

 

Computer scientists design and use the hardware and software of the machines we call “computers.” These machines help people collect and analyze information. Applied Mathematician Bernard Chazelle, Professor of Computer Science at Princeton University, studies natural algorithms: the recipes behind the behavior of flocking birds, cells working together to make the human heart beat, and swarms of insects.

Conservation Biologist

Rae Wynn-Grant

 

Conservation biologists protect Earth’s biodiversity, studying different ecosystems to help the many species of animals and plants living in them survive. Carnivore Ecologist Rae Wynn-Grant studies the movements and other behaviors of the black bears of the Lake Tahoe Basin.

Data Scientist

Alex Pentland

 

Data scientists teach computers to make insights about the world—some that humans can make easily, like telling your best friend’s face apart from your mother’s, and some, like whether you’re likely to get sick or make a new friend, that humans might otherwise miss. Alex Paul (Sandy) Pentland and his colleagues have taught computers to recognize faces and to predict the outcomes of face-to-face interactions, from speed-dating to business negotiations, with remarkable accuracy.

Earth System Scientist

Charles Zender

Earth system scientists ask questions about many spheres: the biosphere (life on Earth, from tiny microbes to giant redwood trees), the atmosphere (the gases surrounding Earth), the hydrosphere (water), and the geosphere (the solid parts of the planet). How do the respiration and photosynthesis of plants in tropical forests affect the rest of the planet? What destroys ozone gas 32 miles above Earth’s surface, in the stratosphere, above the North and South Poles?  How do salty oceans respond to fresh meltwater from receding glaciers? What role do the frozen parts of the geosphere, known as the cryosphere, play in climate change? Earth System and Computer Scientist Charles Zender uses math to create models that help predict how these different spheres interact to produce Earth’s climate.

Sean Gibbons explores microbiomes in many places, from public bathrooms to the human body, in order to study the impact that microbes have on human health.

Environmental Scientist

T.J. Eatmon
Phoebe Romero

Environmental Science is the study of the living and nonliving systems that make up the environment. As Eric Pallant says, “Everybody in the world is confronted with environmental problems locally, regionally or globally.” Environmental scientists like Pallant and T.J. Eatmon use biology, chemistry, physics, and other fields to help solve those problems.

Phoebe Romero works in environmental management and sustainability, helping universities and other organizations save money and protect the environment by conserving energy and water. She also teaches people in different communities the ways that protecting the air, soil, and water will improve their lives.

Evolutionary Biologist

Georgina Cullman

 

How did the different species of animals, plants, and other forms of life come to exist? How, when, where, and why do new species appear?  Evolutionary biologists like Environmental Anthropologist Georgina Cullman study the processes that create Earth’s diverse forms of life.

Evolutionary Genetics

Elizabeth Alter

When you think of evolution, perhaps you imagine a very long tree of life, extending across millions of years, starting with one-celled creatures and ending with us: human beings (Homo sapiens).  But evolution also happens more quickly. The development of antibiotic-resistant species of bacteria is also evolution in action: some of the tiny creatures that cause illnesses in human beings no longer respond to medicine that once cure those illnesses. This challenges doctors and scientists to come up with new ways of protecting people. Evolutionary geneticists like Elizabeth Alter examine DNA and other genetic evidence to help us understand how different species change over time.  Alter focuses her work on oceanic and fresh-water creatures including the mummichog, a fish that lives in polluted water near New York City.

Food Scientist

Aditya Josyula

 

Food scientists like Aditya (A.J.) Josyula study the chemistry, biology, and physics of food and the process of making it. Says Math4Science X-Ray Crystallographer Haroon Malak, “Product developers makes products and we, the scientists, help them understand the science behind them. Someone makes a product and we break it down for them. I love playing the detective and helping people figure out what’s in each product and how to improve it.”

Genetic Engineer

Fyodor Urnov

Genetic engineers make changes in DNA in order to solve problems faced by living organisms. Fyodor Urnov, together with a team of colleagues, uses nanotechnology to repair errors known as “mutations.” These mutations cause genetic diseases such as beta-thalassemia and Huntington’s disease.
