Lei Li might sound like a single name, but it actually points to two very different things. One is the Legal Entity Identifier — a global standard used in finance to uniquely identify companies and organizations. The other is a respected academic — Dr. Lei Li — working at top universities like Carnegie Mellon and UC Santa Barbara. Whether you're trying to understand financial data standards or explore research in artificial intelligence and language technologies, Lei Li is a keyword that pops up in both contexts.
If you're someone who deals with international business compliance, financial transactions, or data verification, the Legal Entity Identifier (LEI) is something you can’t ignore. It’s like a digital fingerprint for companies. On the flip side, if you're into AI, NLP, or computer science, you might be looking up Dr. Lei Li’s work on multilingual AI models or generative systems.
So, what does Lei Li mean for you? Depending on your needs, it could be the key to verifying a company’s identity or discovering cutting-edge research. Let’s break it down and see what each meaning offers and how you can make use of it today.

Who is Lei Li?
Lei Li is a name that appears in two distinct fields — academic research and financial data standards. Let’s first take a look at the person.
Full Name | Lei Li |
---|---|
Current Position | Assistant Professor at Carnegie Mellon University and UC Santa Barbara |
Field of Study | Language Technologies, Computer Science, AI, Natural Language Processing (NLP) |
Education | M.S. from Peking University, Ph.D. (Economics at Stony Brook University or Computer Science in other contexts) |
Research Focus | Multilingual NLP, Generative AI, Representation Learning, LLM Training |
Recent Achievements | 7 papers accepted by EMNLP 2024 including system demos and findings |
Dr. Lei Li is known for his work in language technologies, particularly in multilingual NLP and large language models (LLMs). He has been associated with top institutions like Carnegie Mellon, UC Santa Barbara, and the University of Washington. His academic journey started in China, where he earned his Master’s at Peking University, and continued into the U.S., where he now leads cutting-edge research in AI and machine learning.
What is LEI (Legal Entity Identifier)?
Now let’s switch gears to the other side of Lei Li — the LEI code used in global finance.
LEI stands for Legal Entity Identifier, a 20-character alphanumeric code used to uniquely identify legal entities involved in financial transactions. Think of it like a global ID card for companies. It was created to make financial markets more transparent and reduce risk by clearly identifying who’s who in global transactions.
Here’s a quick breakdown of why LEI matters:
- Transparency: Helps track companies across borders and transactions.
- Security: Reduces fraud by verifying real legal entities.
- Compliance: Required for many financial regulations like MiFID II and EMIR.
- Efficiency: Streamlines reporting and data sharing in finance.
How LEI Works
Each LEI code contains information about the entity it represents. You can look up these codes using the Global LEI Index, which is the official global database. The index is maintained by GLEIF (Global Legal Entity Identifier Foundation) and is open for anyone to access.
Some platforms also act as LEI registration agents, making it easier for organizations to obtain or renew their LEI. You can search for an LEI by country, legal form code, or other filters to find exactly what you're looking for.
How to Use LEI Lookup and Registration
If you need to verify a company’s identity or register for your own LEI, here’s how to get started:
- Visit the Global LEI Index: Start with the official LEI lookup tool.
- Search by Company Name or LEI: You can search using the company’s full name, legal form, or country code.
- Check Validity: Each LEI has an expiration date. Make sure the one you’re looking at is active.
- Register for a New LEI: Use an accredited LEI registration agent to apply. Some platforms allow you to renew existing LEIs as well.
Many financial institutions and regulators now require LEI codes for all transaction parties. If you're doing business internationally or reporting financial data, getting an LEI is a must.
Research Contributions by Dr. Lei Li
Now, let’s go back to the academic side of Lei Li. His research lies at the intersection of natural language processing, artificial intelligence, and multilingual systems. He’s published extensively in top-tier conferences and has contributed to projects like LLaMAX, which explores how to train more efficient and multilingual large language models.
Current Research Focus
- Multilingual Language Models: Training AI systems that work across multiple languages.
- Generative AI: Creating models that can generate text, code, and other types of content.
- Representation Learning: Improving how machines understand and encode meaning from text.
- Preference Learning: Helping AI models better understand user preferences and feedback.
Recent Projects
In 2024, Dr. Lei Li had seven papers accepted at EMNLP, including:
- Three main conference papers
- Three findings papers
- One system demo paper
These works focused on topics like how large language models can be trained more effectively across languages, how to align model outputs with human preferences, and how to build tools that help developers and researchers work better with NLP models.
Frequently Asked Questions
What is an LEI and why is it important?
An LEI is a 20-digit code used to uniquely identify legal entities in financial transactions. It’s important because it makes financial data more transparent, helps prevent fraud, and ensures compliance with global financial regulations.
How do I get an LEI code?
You can get an LEI code through an accredited registration agent. Many platforms offer LEI registration and renewal services, and you can also check your LEI status through the Global LEI Index.
Who is Dr. Lei Li?
Dr. Lei Li is an assistant professor in computer science and language technologies at Carnegie Mellon University and UC Santa Barbara. His research focuses on natural language processing, AI, and multilingual systems. He has published widely and contributed to major projects in machine learning and AI development.
If you're trying to understand financial identifiers or follow the latest in language tech research, Lei Li is a keyword worth knowing. Whether you're verifying a company’s identity or diving into AI research, both meanings of Lei Li offer valuable insights and tools to help you move forward.
