You’ve had an extraordinary career in AI and machine learning, spanning various industries like healthcare, hospitality, and fintech. Can you walk us through your journey and how it has shaped your current role as Director of Advanced Data Science at Marriott International?
I began my professional journey in consumer-focused research for a CPG brand, here I developed a fascination for consumer behaviour change indicated through and their business implications . This passion deepened as I worked on leveraging state-of-the-art machine learning techniques to analyze behavioral changes and their impact on business outcomes. My focus has always been on helping organizations use patterns in data to inform strategy and drive results.
Working in large scale consulting such as Wipro brought me close to enterprises’s pain areas and help create machine learning cored solutions for them. In 2012, I established a Center of Excellence for analytics at Agilis, a lesser-known company at the time, helping telecom clients predict fraud and mitigate risks like churn. Over the years, Agilis went through multiple acquisitions, becoming Infogix and later Precisely Inc. During this period, I led the development of a bespoke software product with an embedded ML-based ‘Anomaly Detection’ system. This solution predicts ‘data drift and shift’, ensuring data quality and integrity. Today, it’s a multimillion-dollar offering used by Fortune 100 companies to maintain operational excellence of data dependent functions.
Currently, as the Director of Advanced Data Science at Marriott International, I lead transformative AI initiatives, including personalization models, generative AI applications, and global acquisition strategies. My journey has been about building scalable AI solutions that align technical innovation with business impact, and I continue to be inspired by the limitless potential of machine learning and AI to transform industries.
In your article, “The Ultimate Blueprint for Enterprise Chatbots: Simplify, Scale, Succeed”, you discuss the challenges of fragmented chatbot strategies. What inspired you to advocate for a unified chatbot framework, and how do you see it transforming industries?
The inspiration came from witnessing the inefficiencies and frustrations caused by fragmented chatbot strategies in enterprises—siloed implementations, inconsistent user experiences, and high maintenance costs. I realized the need for a unified framework that could streamline development, ensure scalability, and provide a seamless experience across touchpoints.
A unified chatbot framework transforms industries by enabling businesses to deliver consistent, personalized interactions while reducing operational overhead. It empowers enterprises to integrate.
Enterprises often face the dilemma of balancing ROI with the complexity of AI solutions. How do you approach this challenge in your projects, and can you share a specific example where you had to make such decisions?
Balancing ROI with AI complexity is a common challenge, but I approach it by focusing on simplification and scalability without compromising value. In my article, The Ultimate Blueprint for Enterprise Chatbots: Simplify, Scale, Succeed, I discussed how fragmented chatbot strategies often create inefficiencies and diminish user satisfaction. To address this, I advocate for a unified framework that prioritizes intent-driven design and reusable components.
A specific example is a chatbot project for a travel enterprise. Initially, individual bots were handling separate use cases like booking management, trip planning, and customer support, leading to redundancy and confusion. By implementing a unified triage bot as the primary entry point, we streamlined user interactions and routed intents to specialized APIs. This reduced operational complexity and boosted ROI by consolidating efforts into a cohesive system.
The result? Enhanced user satisfaction and scalable deployment across multiple business units—all while maintaining a strong ROI through reduced maintenance costs and improved efficiency. Simplifying complexity is not just about technology—it’s about creating value for both users and businesses.
Your work highlights generative AI’s role in creating personalized user experiences, such as credit card recommendations. How do you envision the future of generative AI in personalization across industries?
Generative AI is revolutionizing personalization by creating tailored, intuitive experiences that resonate with individual users. In the context of chatbots, like those for credit card recommendations, generative AI plays a pivotal role in breaking decision paralysis. It simplifies complex choices by presenting relevant options in a conversational and engaging way, helping customers make faster and more confident decisions.
Looking ahead, I envision generative AI expanding its influence across industries—from retail to healthcare—where it will not only personalize user interactions but also anticipate needs, provide proactive solutions, and streamline decision-making. The future of personalization lies in AI’s ability to combine deep contextual understanding with dynamic adaptability, ultimately creating experiences that are both efficient and deeply human-centered.
You’ve authored books, published scholarly articles, and filed patents in advanced AI domains. How do you balance your role as a technical leader and a thought leader in the ever-evolving field of AI?
Balancing my roles as a technical and thought leader in AI comes down to a shared foundation: curiosity , giving back to learners community and a commitment to impact. As a technical leader, I focus on driving practical innovations—building systems like scalable enterprise chatbots or anomaly detection frameworks that solve real business problems. This hands-on work keeps me connected to the evolving challenges and opportunities in AI.
As a thought leader, I view my role as amplifying these learnings for a broader audience. Writing articles on social blogs like “The Ultimate Blueprint for Enterprise Chatbots” allows me to distill complex ideas into actionable strategies, fostering industry-wide collaboration and growth. It’s a synergy—my technical work feeds my thought leadership, while my engagement with the AI community sharpens my ability to lead in dynamic environments.
Ultimately, the key is staying grounded in purpose: using AI not just to innovate, but to inspire and drive meaningful change.
Many of your projects aim to enhance customer experience through AI, like anomaly detection and marketing optimization. How do you align technical innovation with customer-centric outcomes?
I believe the key to aligning technical innovation with customer-centric outcomes is to start with the end in mind—understanding what the customer truly values. Whether it’s anomaly detection, marketing optimization, or enterprise chatbots, my approach combines cutting-edge AI techniques with a deep focus on creating seamless and meaningful experiences for users.
For instance, in my article “The Ultimate Blueprint for Enterprise Chatbots: Simplify, Scale, Succeed,” I emphasized building unified frameworks that deliver consistent, personalized customer interactions. Similarly, my work on marketing optimization involves leveraging predictive models to understand behavioral patterns, enabling hyper-targeted engagement that feels intuitive to the customer.
At the core, it’s about using AI as a bridge—not just to solve technical problems but to anticipate and enhance the customer journey. By embedding intelligence into every interaction, we not only drive business impact but also create solutions that resonate with people in real and tangible ways.
With increasing emphasis on data privacy regulations like GDPR and CCPA, how do you ensure that your AI models remain compliant while delivering actionable insights?
Ensuring compliance with data privacy regulations like GDPR and CCPA starts with embedding guardrails into the design and deployment of AI models. Guardrails ensure that privacy, security, and transparency are foundational, not an afterthought.
In my work, I advocate for privacy-by-design principles—data minimization, anonymization, and secure pipelines are non-negotiables. For instance, when building models for personalized customer targeting or chatbots, we ensure that data used is aggregated and anonymized, aligning with both regulations and user trust.
Balancing compliance with actionable insights requires robust governance frameworks. These frameworks monitor data usage and provide explainability, ensuring that while insights drive business value, they do so ethically and legally. In the age of AI, it’s not just about what we can do with data, but what we should do, and that’s where compliance meets innovation.
As an internationally recognized expert, what advice would you give aspiring data scientists looking to make a significant impact in the field of AI and machine learning?
My advice to aspiring data scientists is simple: focus on solving practical problems and always prioritize the user experience. AI and machine learning aren’t just about building sophisticated models—they’re about creating solutions that make a tangible difference.
Start by immersing yourself in real-world challenges. Learn how businesses operate, identify pain points, and think about how data and AI can address them. For instance, in my own journey, I’ve worked on everything from predictive analytics to creating a unified chatbot framework. These experiences taught me that the best solutions are the ones that simplify complexity and put the user first.
Stay curious, keep experimenting, and don’t shy away from asking questions like: “How does this impact the end user?” and “Is this scalable for enterprise needs?” A data scientist’s true power lies not just in technical expertise but in the ability to translate it into meaningful impact. Keep that as your north star, and you’ll create solutions that truly transform industries.
