Legal Disclaimer & Terms of Use
These terms govern your use of biostatisticsexpert.com and explain the limits of the information it provides.
Last updated: June 2026
Attorney Advertising & Marketing
This website is advertising and marketing for the expert-witness and statistical consulting services of Lei Li, Ph.D., offered through LunarAI LLC. It is intended to provide general information to attorneys and other prospective clients. Some jurisdictions may classify portions of this site as attorney advertising; it is presented in that spirit, while noting that Dr. Li is a statistician and consultant, not an attorney, and does not provide legal services.
No Professional Relationship
Visiting this website, reading its content, or submitting an inquiry through it does not create any attorney-client, consulting, or expert-witness relationship between you and Dr. Li or LunarAI LLC. No such relationship arises from these contacts alone.
An engagement begins only upon a signed written agreement and after clearance of a conflicts-of-interest check. Until both of those steps are complete, no engagement exists and no duties are owed.
Not Advice
The content, articles, and other materials on this website are provided for general educational and informational purposes only. They are not legal, statistical, medical, or regulatory advice for any specific matter, and they do not address the facts of any particular case.
You should not act or rely on any information on this site without obtaining a retained engagement and individualized advice appropriate to your matter. General statistical or regulatory concepts described here may not apply to your facts.
No Guaranteed Outcomes
Descriptions of prior experience, regulatory background, methods, publications, and credentials are provided as background only. They do not predict, promise, or guarantee any particular result, opinion, ruling, or verdict in any matter.
Each matter is assessed on its own facts and data. Dr. Li does not represent that any prior engagement, outcome, or qualification ensures a similar result in your case.
Independence of Opinions
In a retained engagement, Dr. Li's opinions are independent and are based on the available data and generally accepted statistical methodology, regardless of which party retains him. Dr. Li is available to plaintiff and defense alike, and the analysis and conclusions do not change to suit the retaining party.
To date, disclosed litigation work has been in a consulting-expert capacity. Dr. Li welcomes and is available for testifying engagements, including reports, declarations, deposition, and trial testimony.
Former FDA Service & Non-Affiliation
Dr. Li is a former mathematical statistician and primary statistical reviewer with the U.S. Food and Drug Administration (FDA), Center for Devices and Radiological Health (CDRH), and is no longer affiliated with the FDA.
This website is not affiliated with, endorsed by, or sponsored by the FDA or any other government agency. Nothing on this site represents the views, positions, or policies of the FDA. Dr. Li does not offer, and cannot provide, any special access to, influence with, or insider advantage at the FDA. References to FDA experience describe past government service only.
Confidentiality
Please do not send confidential, privileged, or sensitive information through this website or by email before an engagement has been confirmed and a conflicts-of-interest check has been cleared. No duty of confidentiality arises until an engagement is confirmed in writing.
Information transmitted before that point may not be protected and could create conflicts that prevent a future engagement. Dr. Li safeguards the confidentiality of prior clients and does not disclose the parties, counsel, materials, or work product associated with prior engagements.
Intellectual Property & Copyright
All content on this website, including text, layout, graphics, and articles, is © Lei Li, Ph.D., except where otherwise noted. No license or right to use, reproduce, distribute, or create derivative works from this content is granted, whether by implication or otherwise, except with prior written permission.
External Links
This website may contain links to third-party websites or resources provided for convenience only. Dr. Li and LunarAI LLC do not control and are not responsible for the content, accuracy, or practices of any third-party site, and such links do not imply endorsement.
Changes to These Terms
These terms and the content of this website may be updated or revised at any time without notice. Continued use of the site after changes are posted constitutes acceptance of the revised terms. The "last updated" date above indicates when these terms were most recently revised.
Governing Terms
Your use of this website is subject to these terms together with the site-wide disclaimer that appears in the footer of every page. In the event of any conflict between general website content and the terms of a signed engagement agreement, the signed agreement controls for that engagement.
