Career Path Case Studies from Real Chemists: Inspiring Success Stories
Many people imagine chemists as scientists in white coats, lost in a world of bubbling flasks. But the reality is richer and more diverse, especially in analytical chemistry. In this article, I take you inside the world of Dr. Ayesha Rahman, an analytical chemist in Singapore. Through her story, you’ll see the practical side of this field, the challenges, and the rewards. You’ll also get a clear look at how a real person builds a career in analytical chemistry, from university to senior scientist, and what this path demands beyond technical knowledge. This is not a summary or a list of job titles—this is a close-up, real-world case study, told through the eyes of someone living it.
Early Ambitions And First Steps
Ayesha’s journey began in Kuala Lumpur, Malaysia. She was always curious about how things worked, but her interest in chemistry started in high school. "I liked solving puzzles," she shares. "Chemistry was like unlocking secrets no one else could see." She moved to Singapore for her undergraduate studies, enrolling at the National University of Singapore (NUS).
At NUS, she chose a specialization in analytical chemistry. Unlike some of her friends who preferred organic synthesis or biochemistry, Ayesha was drawn to the precision and detective work of analysis. "I realized analytical chemists are the ones who confirm if a medicine is pure or if a water sample is safe.
That felt important to me," she says.
During her third year, she interned at a water quality laboratory. This first industry experience was eye-opening. She learned that analytical chemistry was not just about using machines—it was about asking the right questions, understanding regulations, and communicating findings clearly.
Ayesha noticed that compared to theoretical work at university, the lab’s daily routine was filled with real-world consequences. If she made a mistake in calculating a concentration, it could lead to a failed batch or the need to repeat hours of work.
She remembers her supervisor reminding her, “In this lab, your results can decide if water is safe to drink. ” This sense of responsibility was new but motivating.
She also found that analytical labs are not just about numbers and results. There is a big human element—collaborating with technicians, discussing results with engineers, and sometimes explaining data to managers who aren’t scientists. This early exposure helped her realize that communication is as important as technical skill.
Many students underestimate how much time is spent interpreting results for non-chemists.
Transition From Academia To Industry
After graduating, Ayesha faced a big choice: continue with a master’s or start working. She chose a job as a junior analytical chemist at a pharmaceutical company in Singapore’s Tuas Biomedical Park.
Her first months were tough. "University teaches you the science," she explains, "but the industry is about speed, accuracy, and teamwork. The machines are bigger, the samples never stop, and small mistakes can cost money or even patient safety. "
She spent her days running high-performance liquid chromatography (HPLC) and gas chromatography (GC) tests. Her role was to check the purity of active ingredients and finished drugs. Each test followed strict Standard Operating Procedures (SOPs). She quickly learned to manage her time, double-check her work, and ask for help when she was unsure.
But Ayesha also noticed something beginners often miss: lab work is just one part of the job. Much time is spent on documentation, writing reports, and communicating with quality assurance teams. "If you can’t explain your results, it’s like the work never happened," she says.
She recalls her first audit, where she had to defend her data in front of an inspector. The experience was nerve-wracking but taught her to always keep detailed notes. Auditors often ask for records from months ago, and being able to quickly find and explain past work builds trust with regulators and managers.
Ayesha learned that strong documentation not only protects the company, but also her own professional reputation.
Another area that surprised her was the importance of teamwork. In school, she mostly worked alone, but in industry, projects often require coordination with other chemists, engineers, and even production staff. She learned to adjust her communication depending on her audience—for example, simplifying technical details for non-scientists.
These “soft skills” are rarely taught in university but make a big difference in the workplace.
Gaining Skills And Responsibility
After two years, Ayesha was promoted to Analytical Chemist. Now she had her own projects and sometimes trained new hires. The most important skill she developed was troubleshooting. Machines break, samples behave strangely, and sometimes results make no sense.
"Being able to think critically and not panic is key," she advises. For example, she recalls a time when an HPLC instrument gave strange peaks. Instead of re-running the samples blindly, she checked the mobile phase, cleaned the column, and recalibrated the detector.
The problem was a small air bubble in the tubing—easy to fix, but only if you know what to look for.
She also learned that method development is a creative process. Sometimes, the standard methods don’t fit a new drug or impurity. Analytical chemists must adjust parameters, try different columns, or even build new methods from scratch, always validating their work.
Ayesha shares that one of her favorite projects involved developing a method to detect a new trace impurity in a complex formulation. The first attempts failed—signals were too weak, and background noise was high. She had to research new solvents, test different detector settings, and consult with a more experienced chemist.
Through trial and error, she finally succeeded. This experience taught her the value of persistence and creative problem-solving.
She also began mentoring junior staff. Teaching others forced her to clarify her own thinking and stay updated on best practices. Ayesha found that explaining the “why” behind each step helped new chemists avoid common mistakes and improved overall lab performance.
Another less obvious skill is time management. With many samples to test and deadlines to meet, she learned to prioritize urgent work, plan her day efficiently, and communicate delays early. Good time management reduces stress and helps prevent errors that can occur when rushing.
Moving Up: Senior Analytical Chemist
Today, after seven years, Ayesha is a Senior Analytical Chemist. Her responsibilities cover:
- Developing and validating new analytical methods
- Training junior staff
- Managing compliance for audits and regulatory reviews
- Coordinating with R&D, production, and quality teams
She works closely with regulatory bodies like Singapore’s Health Sciences Authority (HSA) and sometimes with international agencies such as the U.S. Food and Drug Administration (FDA). "Audits are stressful," she admits, "but if your documentation is clear and your results are solid, there’s nothing to fear."
A typical week involves a mix of hands-on lab work, meetings, and paperwork. She might spend a morning optimizing a new method for detecting a trace impurity, then review data with the quality manager, and later write a technical report for an upcoming product launch.
Ayesha often leads investigations when unexpected results occur. For example, if a batch fails a purity test, she must quickly gather data, review procedures, and suggest corrective actions. These investigations require both technical skill and diplomacy, as mistakes can have serious business or regulatory consequences.
As a senior chemist, she is also involved in strategic discussions about new technologies for the lab. She helps evaluate new instruments, tests software upgrades, and sometimes presents findings to upper management. This exposure to the “big picture” has helped her understand how analytical chemistry fits into the company’s goals.
She also mentors a small team, reviewing their work for accuracy and coaching them through difficult problems. This role is rewarding but also challenging, as she must balance her own projects with supporting others.

Key Tools And Technologies
Ayesha’s lab is filled with advanced instruments. The main ones include:
- HPLC: Used for separating and measuring compounds in a sample.
- GC: Ideal for volatile substances and solvents.
- Mass Spectrometry (MS): Paired with HPLC or GC for identifying unknowns.
- UV-Vis Spectroscopy: For quick, routine analysis.
- Titration and Wet Chemistry Tools: Still important for some tests.
Below is a comparison of common analytical instruments used in Ayesha’s lab:
| Instrument | Main Use | Strengths | Limitations |
|---|---|---|---|
| HPLC | Separation and quantification of drugs, impurities | High sensitivity, wide range of compounds | Needs careful method development |
| GC | Analysis of volatile compounds | Fast, reliable for small molecules | Not suitable for large or non-volatile molecules |
| MS | Identification and structure analysis | Precise, very sensitive | Expensive, needs expertise |
Ayesha emphasizes that while knowing how to run an instrument is important, understanding the science behind the method is what sets top analytical chemists apart.
She often sees new chemists who can operate a machine but struggle to interpret unusual results or suggest improvements. For example, understanding why a peak splits on a chromatogram can reveal issues with sample preparation, instrument maintenance, or method design.
This deeper knowledge comes from experience and a willingness to learn beyond the manual.
Her lab is also investing in automation and digital data systems. Automated sample preparation and advanced software for data analysis are becoming common. These technologies reduce repetitive work and help chemists focus more on problem-solving, but they also require new skills in programming and data management.
Challenges In Analytical Chemistry
No career is perfect, and Ayesha is open about the difficulties. One big challenge is pressure to deliver results quickly. Pharmaceutical timelines are tight, and delays in analysis can stall a whole project.
Another is regulatory compliance. Every step must be documented. Even small deviations need to be explained and justified. "You can’t just say, ‘The sample looked fine,’" she jokes. "You need data."
There are also physical demands. Long hours in the lab, repetitive tasks, and sometimes exposure to chemicals make safety protocols critical.
But perhaps the biggest challenge, especially for new chemists, is managing uncertainty. Not every test gives a perfect result. Sometimes, no one knows why a problem happened. Ayesha recommends staying calm, building a network of experienced colleagues, and never being afraid to ask questions.
She points out that learning to say “I don’t know, but I will find out” is a sign of professionalism, not weakness. Many new chemists feel pressure to have all the answers but being honest about limits and seeking help leads to better outcomes.
Another hidden challenge is keeping up with changing regulations. Guidelines from agencies like the FDA or HSA are updated regularly. Ayesha spends time reading new documents and attending training sessions to stay compliant. Missing a regulatory update can mean extra work or even failed audits.
She also warns about “analysis paralysis. ” With so much data, it’s easy to get stuck looking for the perfect answer. Experienced chemists learn when more testing is needed and when to trust their results and move forward.
Work-life Balance And Culture
Ayesha’s company values work-life balance, but there are busy seasons—especially before audits or big product launches. "Some weeks are 40 hours, others can be 50 or more," she says. She manages stress by scheduling small breaks, staying organized, and making time for family and hobbies.
Singapore’s multicultural environment brings its own flavor to the workplace. Teams are diverse, with colleagues from China, India, Malaysia, and beyond. Communication is mostly in English, but technical language can still be a barrier for some.
Ayesha also notes that women are well-represented in Singapore’s pharmaceutical labs. "There’s a lot of support for women in STEM here," she says, though leadership positions are still male-dominated.
She finds that celebrating small wins—a successful audit, a new method working, or a team lunch after a busy week—helps build team spirit. She also appreciates flexible work options, such as remote meetings and staggered hours, which have become more common after the COVID-19 pandemic.
One insight she shares is the importance of building relationships outside her immediate team. By joining social events or volunteering for cross-department projects, she has expanded her network, which often leads to new opportunities or support during tough times.
