Governor Josh Shapiro appointed Lucas M. Miller to continue serving as State Inspector General, after serving under Governor Tom Wolf as the eleventh Inspector General of the Commonwealth of Pennsylvania. Previously, he served as the First Deputy State Inspector General, where he oversaw the office's daily operations and its transition to the law enforcement agency it now is.

Miller has been with the Office of State Inspector General (OSIG) for over twenty-four years, beginning his career as an Agent in OSIG's Bureau of Fraud Prevention and Prosecution (BFPP). He has held numerous positions within the Office, including Welfare Fraud Investigator Supervisor; Operations Manager; Bureau Director for the Bureau of Administration, Policy, and Training; Bureau Director for BFPP; and First Deputy State Inspector General. Miller has had the opportunity to interact with all aspects of the agency and with individuals from across the Commonwealth. He has fought to ensure that everyone, no matter their situation, is treated with respect and dignity.

Miller has significantly improved the agency in many ways, particularly focusing on increasing government efficiency through streamlining processes. He has led multiple internal program reviews, consolidated two program bureaus into one, and helped create an electronic case management system. Under Miller's direction, OSIG and DHS developed and implemented an Electronic Referral System which removed wasteful processes, eliminated all paper, allowed for instantaneous referrals of investigations, optimized travel to DHS County Assistance Offices, and greatly limited costly physical file storage. These initiatives allowed OSIG to be fully prepared for a shifting work environment with greater emphasis on mobility and field operations.

Miller's vast experience within the agency has uniquely qualified him for the role of State Inspector General. OSIG's mission is to stop fraud, waste, misconduct and abuse in programs, operations, and contracting of executive agencies. By accomplishing that mission through accountability and program integrity, Miller works every day to increase the trust the citizens of Pennsylvania have in their government.

Miller has spent his career working to make state government function better. OSIG's success in improving government operations and investigative processes have not gone unnoticed nationally, and Miller has presented at conferences across the United States.

Miller is a Certified Inspector General by the Association of Inspectors General and a distinguished graduate of the Virginia Military Institute.​​
