Sayani Majumdar, a leading expert in neuromorphic computing and a former singer, is making strides in replicating the efficiency of the human brain in computing. Her work focuses on developing cutting-edge hardware designed to support this emerging technology. Currently serving as an associate professor at Tampere University in Finland, Majumdar has dedicated her research to improving AI efficiency through innovative hardware solutions. Beyond her academic pursuits, she enjoys Darjeeling loose-leaf tea and embraces her heritage through music.
A Journey from Calcutta to Finland: Building a Research Career
Originally from Calcutta, India, Sayani Majumdar has spent years in Finland, shaping her career in research and academia. She arrived in Turku with her husband when their eldest son was just a few months old, a transition that marked the beginning of a new chapter in both her personal and professional life. The couple lived in Turku for nearly a decade, and the city remains close to her heart.
As a young mother in a foreign country, Majumdar initially faced isolation. However, she secured a scholarship through a university-backed private foundation, allowing her to on her first research project. This opportunity laid the foundation for her academic career in Finland and paved the way for her contributions to neuromorphic computing.
Finland’s Research Environment: Balancing Work and Life
One of the aspects Majumdar appreciates most about Finland is the supportive research environment. The country’s trust-based academic system provided her with the flexibility needed to balance motherhood and research. Finnish childcare services also played a crucial role in her journey, allowing her to focus on her career with peace of mind.
The work-life balance in Finland fosters academic productivity without compromising personal responsibilities, making it an ideal place for researchers like Majumdar to thrive.
The Potential of Neuromorphic Computing
Neuromorphic computing takes inspiration from the human brain, seeking to create more adaptive and energy-efficient computing systems. Traditional computers, while powerful, struggle with the high energy demands required for AI-driven data processing. Majumdar’s research aims to bridge this gap by developing hardware that mimics the efficiency of the brain.

Unlike conventional computers that continuously transmit data, the human brain processes information using spikes, making it significantly more efficient. AI models today consume vast amounts of energy to process massive datasets, a challenge that neuromorphic computing seeks to address. By designing chips that process data locally—closer to sensors—this technology can drastically reduce power consumption and improve computational efficiency.
A prime example is in healthcare. Smart heart monitors utilizing neuromorphic chips can transmit only critical data, such as irregular heartbeats, to doctors instead of continuously sending large streams of data, thereby saving energy and bandwidth.
Applications of Neuromorphic Computing
The applications of neuromorphic computing extend across various industries:
- Autonomous Vehicles: By enabling real-time data processing within sensors, neuromorphic chips can enhance decision-making and improve safety.
- Security Systems: Adaptive learning capabilities allow systems to detect anomalies more effectively.
- Space Exploration: Given the limited power available in space missions, energy-efficient neuromorphic computing is ideal for autonomous operations on distant planets like Mars, where communication delays make real-time Earth-based guidance impractical.

Addressing AI’s Growing Energy Demands
A 2019 report highlighted that training a single AI model consumes the same amount of carbon as five cars over their lifetimes. With AI models growing more complex, energy consumption has surged. While software innovations continue, hardware advancements struggle to keep pace. Neuromorphic computing presents a sustainable alternative, offering an energy-efficient solution for the future of AI.
Energy Savings and the Path to Adoption
Neuromorphic computing has the potential to save up to a million times the energy used by conventional computing devices. However, full-scale adoption will take time. Research currently focuses on hybrid systems that integrate both traditional and neuromorphic components to optimize energy efficiency.
The Need for Hardware Innovation
Beyond device-level improvements, Majumdar emphasizes the importance of hardware architecture innovation. To unlock the full potential of neuromorphic chips, new algorithms must be designed specifically for these advanced systems. The challenge lies in adapting AI frameworks that are traditionally built for older hardware models.
Collaboration and Industry Involvement
Majumdar actively participates in international collaborations, including a project with the University of Massachusetts focusing on pressure sensor-based computing. Despite the high costs associated with hardware development, industry partnerships with leading companies such as IBM, Intel, and Samsung are helping drive this technology forward.
Passion for Music and Tea: A Personal Side
Majumdar finds joy beyond research through music and tea. Trained as a singer by her mother, she enjoys performing songs from her Calcutta heritage, which often explore themes of nature, love, and spirituality. This passion provides her with a sense of calm and connection to her roots.
Similarly, she has a deep appreciation for Darjeeling loose-leaf tea, which she prepares traditionally without milk or sugar. The ritual of brewing tea is a cherished daily routine that keeps her grounded.
