I am Stephy Jose, a postdoctoral researcher currently working at the Tata Institute of Fundamental Research (TIFR), Hyderabad. From a young age, I was drawn to science, curious about how things worked. Physics, in particular, interested me — not because it was easy, but because it wasn’t. It always felt mysterious, like it held secrets about the universe waiting to be discovered. Ironically, physics was also the subject where I scored the least in school, but that only made me want to understand it more. 

I pursued a Bachelors in Physics from Mahatma Gandhi University, Kerala, and later a Masters in Physics from University of Hyderabad. In 2019, I joined TIFR Hyderabad for my PhD under Kabir Ramola, focusing on ​“Hydrodynamics and fluctuations in models of active particle motion.”

My research – Understanding active matter

My PhD research centred on understanding active matter—systems made up of self-propelled entities that move using their own internal energy. These range from humans and animals to bacteria and synthetic particles. Have you ever seen a flock of birds or a school of fish move in perfect sync? Even microscopic bacteria exhibit collective motion, forming dynamic clusters. My work involved developing mathematical models using tools from Statistical Physics to understand how these entities interact, and self-organise into clusters, waves, or other emergent structures. A major focus of my research was on how noise or unpredictability influences their motion, how they decide where to go next, and how their initial conditions — like their starting positions affect their future trajectories. 

Applying for postdoctoral positions – A real struggle

I started applying for postdoctoral positions six months before completing my PhD. Looking back, I would say the earlier you start, the better. The best time to apply is during the fall (September – December) and spring/​summer (March – June) cycles, when universities advertise open positions. 

The process, however, was far from easy. Openings in my specific field were rare, and when positions did exist, they were competitive. I reached out to experts in my field, but many simply didn’t have funding. I considered switching fields, but most labs preferred candidates with prior experience, as postdocs are expected to deliver results quickly. The constant rejections made the journey disheartening. I reached out to Hartmut Löwen, Professor at Heinrich Heine University (HHU), Düsseldorf, Germany and he suggested applying for externally funded fellowships. This would allow me to work independently on problems I was passionate about, without being tied to a lab’s existing grants. 

What is the Humboldt Fellowship and when to apply?

The Alexander von Humboldt Foundation offers a prestigious research fellowship for postdocs and experienced researchers — the Humboldt Research Fellowship—which allows international scientists to conduct independent research in collaboration with a German host. It provides generous financial support, family benefits, and language courses. 

One of the biggest advantages is the Humboldt Network, which facilitates long-term professional relationships, and career growth opportunities. Plus, you get to explore Germany, from historic sites to stunning landscapes — who wouldn’t love that? 

If you have finished your PhD within the last four years (for postdocs) or twelve years (for experienced researchers), you are good to go! Strong publications, a solid research plan, and a potential host in Germany are key. Your host should be someone actively working in your field, who is enthusiastic about mentoring you. The best part? No fixed deadlines! You can apply anytime. But don’t let that fool you into procrastinating — processing takes months, and securing a strong host is crucial. I would say, give yourself at least six months before you hope to start. 

My journey – A moment of reflection

Although I was enthusiastic at the beginning of my PhD, I felt a noticeable decline in that energy as I approached the end. Writing papers, revising manuscripts, working on thesis, and giving seminars became routine. Somewhere along the way, the deep curiosity that once drove me started to wane. This made me question myself. I had everything required for a successful PhD — enough publications, solid research — but I lacked something more profound: satisfaction. I always wanted to continue in academia, but I wondered whether I would excel in this field? Could I guide students effectively?

At the same time, I wanted to explore new directions. My research so far has been largely theoretical. But I wanted to see my abstract ideas come to life. That meant stepping into unfamiliar territories. Could I excel in a new field?

One thing I appreciated about the Humboldt Fellowship was that it gives me the freedom to take that risk. The rest, I would figure out along the way. I hope this opportunity helps me understand where I stand and what I truly want to do. For now, I am committed to giving it my 100%. 

How I applied

My journey started with identifying a host whose work closely aligns with my interests. I also received valuable feedback from my PhD supervisor and previous fellows. The application included:

• A research proposal (after multiple iterations!)

• A CV and publication list (quality over quantity)

• Reference letters (preferably from people who really know your work)

• A support letter from the host scientist in Germany (someone established and excited to work with you!)

One of the unique aspects of this fellowship is that there is no interview. Selection is purely based on your application documents. This means that every document must be crystal clear and compelling.

Tips for a good research proposal

• Strong research idea – Should be well-thought-out, either building on your PhD work or exploring a new direction.

• Think broadly and ambitiously – Consider the bigger picture and the potential impact.

• Clarity and precision – The first paragraphs should clearly state your research objective, why it is important, and how it differs from existing work. It should be understandable by non-experts.

• Well-structured format – Use well-defined sections with headings for readability.

• Use visual elements – Include figures with captions to enhance understanding.

• Detailed methodology and research plan – Clearly outline your plan. 

• Include preliminary results – Strengthens your case.

• Future directions – Show that you have a long-term vision.

• Your unique fit – Considering your expertise and background.

• Role of the German host – Describe how they will contribute and what you will bring to their institute.

• Page limit – Maximum 5 pages, excluding references.

• Compelling conclusion – End with a strong closing statement.

My biggest advice? Start early, find the right host, and don’t hesitate to seek feedback on your proposal. If you enjoy research, collaboration, and a bit of adventure, this fellowship is a fantastic opportunity. 

I believe in hard work and smart work, guided by honesty, compassion, and discipline — values that shape both my personal and professional life. Every day feels like an opportunity to learn something new, and I find it difficult to sit idle. There is so much to explore, and life is too short to let it pass by without purpose. And who knows? Maybe your next big idea will take shape over a cup of German coffee!
