Most of us are surprised by your utmost discipline and dedication in life. Please shed some light on this aspect, especially for women who still have some reservations with respect to the art of balancing work and personal life. 

RB: I definitely faced a number of challenges along the way to this breakthrough, including trying to balance my full-time Masters’ program at Carnegie Mellon University with my passion for Data Science. Managing my time effectively was crucial, as I had to make sure I had enough time to complete my coursework and contribute on Kaggle. As I participated in new Kaggle competitions, I needed to also brush up on the latest developments in the field by reading a lot of research papers.

However, I never let these challenges get in the way of my motivation to learn and grow as a Data Scientist. I actively sought out opportunities to improve my skills and network with others in the industry, and I made sure to stay proactive and focused on my goals. 

I believe that the key to overcoming challenges in any field is to stay motivated and continue learning and growing as a professional. With the right mindset and a willingness to put in the work, you can achieve anything you set your mind to. So, never give up on your dreams!

 

AV: Data Science is still at a nascent stage, and not many women are part of this industry. Please share some career advice for girls who are planning to start their careers or want to transition into this field.

RB: First and foremost, it is essential to continuously learn and develop your skills. The field of Data Science is constantly evolving, and it is essential to stay up-to-date with the latest tools and techniques. You could even consider getting a degree in a related field to ensure you have the skills you need to succeed.

Networking and building relationships are also crucial in Data Science. By joining professional organizations and attending industry events, you can connect with other professionals and learn about potential job opportunities. Don’t be afraid to ask for help when you need it – consider seeking guidance from experienced professionals or finding a mentor to help you navigate the field.

Finally, be persistent and don’t give up. Breaking into any new field can be challenging, and Data Science is no exception. However, with dedication, you can build a rewarding career in this field. So don’t let setbacks or challenges deter you – stay focused on your goals and keep working towards them.

 

AV: Do you recall when you decided to be part of the Data Science and Analytics world? Did you receive any guidance from people?

RB: Data Science can play a massive role in changing the present. It is a rapidly evolving field with a lot of scope for research to address the day-to-day challenges people face. I’ve always been interested in the intricacies of languages, and being multilingual has added to my inclination toward Natural Language Processing and its powerful applications today. This is what influenced me to pick Data Science as my career choice.

Mentors are undoubtedly crucial for everyone to gain a sense of direction, be it in any domain. We need a bubble of positivity and just the right amount of encouragement to reach our goals.

My mother has played a huge role in encouraging me to pursue my dreams right from the early years of my life when I dreamed of becoming a Computer Engineer, to this day, in a field where we’re constantly faced with new challenges to solve!

 

AV: Which women in DS inspire you?

RB: Daphne Kohler because of her ground-breaking contributions in the Data Science and Machine Learning space and co-founding Coursera, a platform I’m sure most of us have turned to.

I’ve earned a lot from her Probabilistic Graphical Models course on Coursera. She has phenomenal knowledge and an excellent grasp of concepts which she passes on to us.

 

AV: You’re currently a Data Science Global Ambassador at HP and the Leader of Data Science at OpenMined. These are prestigious positions. Would you like to share some of your learnings along the way?

RB: As a Data Science Global Ambassador at HP, I have been fortunate enough to have access to local GPUs that have greatly enhanced my Data Science workflows. These resources allow me to run a large number of experiments concurrently without any time constraints, which is especially valuable as data size continues to increase and cost and time become critical considerations. The high-quality equipment I have been provided has significantly increased my productivity and efficiency by enabling me to run more experiments and save time. Additionally, it allowed me to expand my professional network immensely and provided me the opportunity to work with some of the best minds in the field! It’s also an enabler for keeping me motivated to actively contribute to the community.

Through OpenMined, I was able to dive into the world of Private AI, and I worked on privacy-preserving machine learning and artificial intelligence technologies. Last year, our team also collaborated with Twitter to allow third parties to access non-public Twitter data using privacy-preserving technologies, enabling them to investigate topics such as the amplification of political content by Twitter’s recommendation systems without exposing any user’s private data or any of Twitter’s models or intellectual property. All in all, it was a fascinating initiative and a valuable learning experience for me!

 

AV: We would like you to share some tips and tricks that have worked for you in the past. With people who are aspiring to build a career in the Data Science Industry. 

RB: Some tips and tricks that worked for me in the past were: 

Finding my area of interest – This helped me to stay motivated and persevere through the challenges I faced as a beginner.

Making reading a regular part of my routine – Setting small targets helped me a lot, whether it was reading a certain number of blogs or research papers each day or week.

Staying up to date on technology trends by reading relevant sources, such as the MIT Technology Review – Keeping track of articles I’ve enjoyed reading by creating a personal document sorted by category. This helped me whenever I wanted to refer back to something in the future and saved me plenty of time.

Project-based learning – I preferred a more hands-on approach to learning important concepts.

 

AV: I believe, Kaggle has been a backbone to achieving this milestone in your life. Please share how it helped you to strengthen your portfolio.

RB: I attribute my success to a combination of consistency, patience, and curiosity, which are essential qualities for anyone looking to achieve their goals. I am grateful to both Kaggle and Z by HP for providing me with the resources and opportunities to develop these qualities and put them into practice.

Kaggle has been particularly instrumental in my journey. It has provided me with a safe and supportive space for exploring and learning about a wide range of concepts and techniques that cannot be found in traditional courses. By focusing on project-based learning after joining Kaggle, I have been able to apply my knowledge and skills in a real-world context rather than just learning about a subject in a theoretical or abstract way.

 

AV: As we close this conversation, We would love to hear some words of inspiration for ‘Women in Data Science’ from you. 

RB: Imposter syndrome is a common experience among beginners, especially with the prevalence of social media highlighting the successes of others. It’s easy to fall into the trap of comparing ourselves to others and forming an idea of what success should look like based on what others have achieved. But the truth is, we all have our own unique stories and motivations that have brought us to where we are today, and that’s what makes us each capable of pursuing our passions and goals.

Don’t be afraid to speak up and share your thoughts and ideas. Your opinion is just as valuable as anyone else’s, and it’s important to let your merit and abilities define you.

Remember to cultivate a positive, growth mindset and tell yourself that you can achieve anything you set your mind to. Don’t let fear or self-doubt hold you back from pursuing your dreams and reaching your full potential.

 

Conclusion

Parting ways, I can’t help but reiterate the fact that gender has got nothing to do if you have the grit and zeal to make it big in your niche. All you need is perseverance and a deep-rooted passion for your subject, and the sky’s the limit! We would love to hear your thoughts and learnings from this interview.
