For many of us, medicine is the sought after solution for a cold, flu, or allergy. It can be the promise of a cure or a healthier lifestyle. For Joanna Tong, medicine is much more than that. It is the opportunity to make an immediate and tangible impact on the lives of those overcoming chronic illnesses. As the Senior Technical Manager for Genentech, Joanna is primarily focused on the overall quality of the medicine, its production, and its ability to be transported to different companies.

As a young student, Joanna enjoyed biology and genetics, and considered becoming a biologist early in her career. While studying at the Massachusetts Institute of Technology, she was exploring different paths that aligned with her ambitions, when a professor recommended chemical engineering. After taking a few classes in the field, she grew to like the discipline because it empowered her to think outside of the box.

“In school, I did traditional lab work, however I found it more interesting to utilize technical problem-solving skills that are involved with engineering.”

Joanna put her skills to the test when she began interning at Genentech, over 10 years ago. Genentech gave Joanna the chance to dip her foot into the biotech and pharmaceutical worlds and allowed her to realize how much she loved the work she was doing.

“When I say that I help ensure we make high-quality medicines for patients, most people don’t realize that the medicine we make is quite different and much more complex than the pills you would see at your local pharmacy. Most of the medicines Genentech makes are proteins that are delivered via an IV infusion at a hospital, and those proteins are made by live cells that we grow in giant bioreactors. You have to control for and understand so many variables to keep the cells happy and producing the protein you want. It’s an incredibly complex process.”

Joanna spent most of her career as a Manufacturing Engineer, which plays an essential role in Genentech’s production of high-quality drugs. The complex drugs could aid those with serious medical conditions such as colon cancer, lung cancer, multiple sclerosis, and arthritis. One of the many important part of that role was making sure that the medicine-producing cells were effective and safe. Now, as a Supplier Collaborations Technical Manager, Joanna’s tasks are less focused on the manufacturing process and more on collaborating with suppliers.

“I work with the suppliers that give us the ingredients and equipment we use to make our medicines. It’s important to partner with them because if we don’t have good starting materials, it’s hard to have good quality come out the other side.”

As one of the only girls in advanced math and science classes early in her educational career, Joanna understands what it is like to be a minority in a technical field. Because of this, and in addition to her job, she now serves as the Regional Lead for Pharma Technical Operations Women Professionals at Genentech. Through this organization, she develops programs and organizes monthly events that help over 1000 women in the Pharma Technical Operations in the Southern San Francisco organization accomplish their career objectives while building the company’s pipeline of future leaders.

“I think opportunities for women in STEM are already changing and increasing. I’ve been lucky enough to have worked for a lot of amazing women leaders. It helps to have role models and mentors.”

How Vanessa Evoen’s Childhood Dream Became a Vision for Global Impact

Unlike most young people, when asked what she wanted to be when she grew up, Vanessa Evoen had an unwavering answer-- she wanted to be an engineer. Although Vanessa excelled in many different disciplines, such as fashion and art, she never had to convince herself to love the dynamics of engineering.

Although currently based in California, growing up, Vanessa was constantly exposed to a variety of different places and it was her time in Lagos, Nigeria at the Vivian Fowler Memorial College for Girls that fostered her love of STEM.

“When I went to the all girls school in Nigeria, I took an introduction to technology class, and I remember it being so fun to learn how to build and create different things.”

After that initial experience, Vanessa engulfed herself in other STEM-related classes, including a technical drawing class where she learned how to fabricate isometric drawings by hand. Her continued excitement for learning how to develop plans for houses and machine parts sparked her interest in aerospace engineering. Her familiarity with travel encouraged her to study planes, however, her plans quickly changed after taking her first organic chemistry class.

“I remember it being one of the best classes I had ever taken, because it came to me so naturally. I never had direct guidance in picking a discipline for engineering, but I have a good memory which is useful in chemistry, so I combined it with engineering.”

After completing a summer research program at the University of California, Los Angeles, it was clear to Vanessa that she wanted to do experiments in technical fields. While working on her undergraduate degree at UCLA, Vanessa dove into research dealing with semiconductor fabrication, a process that produces integrated circuits that power a variety of electronic devices. She enjoyed studying the individual components of solar cells and their ability to convert energy into electricity.

Vanessa’s passions for the applications of energy led her to graduate school.  The eager scholar knew she wanted to attend one of the top two schools in her field at the time, which were MIT and Caltech. Vanessa admits she faced imposter syndrome after being accepted into Caltech. With an acceptance rate of less than 9 percent, she remained steadfast in her purpose of pursuing a PhD.

“Engineering at Caltech is a tough program to get through, and you really have to find your footing,”  said Vanessa. “Rather than focusing on how to get an A or how to have the best paper, I was more concerned on whether my experiments worked. I just knew my passion and why I was there.”

While at Caltech, the chemical engineer diversified her skill set by transitioning her focus to fuel cells and discovering how chemical energy can be converted into electrical energy. Although Vanessa enjoys her current work as a Plasma Etch Engineer at Lam Research, her experience of growing up in different parts of the world gave her a unique perspective and a desire to make a global impact.

“It’s pretty amazing that something I work on everyday is used by the average consumer, but my plans are more than what I am doing right now,” explained Vanessa. “Nigeria is one of the top ten oil producing countries in the world without constant electricity. I am always thinking of ways I can give back and what I can do to change that.”

As the first black women to receive her PhD at Caltech, Vanessa also hopes to excite more young individuals to enter STEM related fields. Furthermore, she created the platform, Vannyetal.com, to share stories, lifestyle tips, and mentor others.

“We need more people, especially women to pursue STEM. I know that I am the only person that looks like me in the lab, but I remember why I do what I do and I know that I can do it. I want others girls to have a mentor to encourage them to know they can achieve in STEM, too.”
