Dr. Erika Angle

Meet Biochemist Dr. Erika Ebbel Angle, the force behind Ixcela. Erika serves as Chief Executive Officer, President and Director of Ixcela. She is a graduate of M.I.T. and received her Ph.D. in Biochemistry from Boston University School of Medicine.

“I’ve been working on and testing ways to improve my own personal internal fitness and well-being for over a decade. I founded Ixcela to create better and more effective natural, science-backed interventions and make them readily available to everyone.”

Internally yours,


Dr. Wayne Matson

Dr. Wayne Matson is Co-Founder of Ixcela and serves as its Chief Scientist. He has been at the center of the field of metabolomics for 30 years. He holds a Ph.D. from M.I.T. and is considered a “father of modern metabolomics.”

Dr. Matson founded ESA Biosciences, Inc., one of the first Massachusetts-based biotech start-ups, in 1968. At ESA, he developed the leading global test for childhood lead poisoning, as well as tests for iron deficiency, separations research, and various novel diagnostics. He holds over 100 patents.

“One of the reasons I founded Ixcela was to bring years and years of research and technology out of the lab and into real, actionable diagnostics and therapeutics that can help to create better health for all.

The “Metabolomic Network” is complex and still not fully defined by any one technology. However, there exist biomarkers reflecting metabolomic/genomic interactions and by testing and analyzing your gut microbiome/metabolome we can gain insight into what therapeutic actions can be taken to reduce chronic disease risk and create and maintain overall better wellness. That’s been my scientific passion and life’s work.”



Ixchel or Ix Chel (Mayan) is the name of the goddess of healing and medicine in ancient Mayan culture.


Ixcela: The Internal Fitness™ Company Summary

Ixcela: The Internal Fitness™ Company is a hard science based company that helps individuals improve their internal fitness. For a variety of lifestyle related reasons, the body’s internal biochemistry can be moved from a healthy balanced state to a state that can lead to chronic disease. These chronic conditions include Alzheimer’s, Parkinson’s, ALS, and diabetes. Additionally, poor internal fitness may cause less severe, but more common health issues such as irritable bowel syndrome, acid reflux, and leaky gut.

The Ixcela approach is focused on restoring internal fitness by a sophisticated test which identifies key small molecules associated with the gut microbiome that are out of balance, and an individualized therapy which restores these molecules to their proper levels through a personalized program which includes proprietary supplements specifically targeted at improving gut microbiome health.

Ixcela has developed a pin-prick blood test which looks at the levels of 12 unique small molecule metabolites shown through experimentation, peer reviewed literature and clinical studies to be associated with gut microbiome health. Analysis of the blood spot is performed by proprietary technology including the Electrochemical Array (CoulArray) invented by our co-founder Wayne Matson. Ixcela is also developing unique supplements to help regulate the specific biomarkers that are not at optimal levels. Thus, Ixcela provides a comprehensive approach to a) determining gut microbiome dysbiosis and b) providing actionable solutions to restoring proper gut microbiome health and ultimately improving internal fitness.

The Ixcela leadership team brings together proven successful entrepreneurial experience including multiple exits with world-class science. Our Pinnacle award winning CEO Erika Angle, Ph.D. (Biochemistry) partners with our Chief Scientist Wayne Matson, Ph.D., founder of ESA, Inc., who is the inventor of the Electrochemical array (CoulArray) and the hand-held lead blood test used extensively to monitor childhood lead levels, amongst many others.

Our board currently includes: Colin Angle, CEO, Chairman, Co-Founder of iRobot; a manufacturer of consumer and military robots; Heiner Dreismann, former CEO of Roche Molecular Systems, Nick Soloway, Patent Attorney of Hayes Soloway, Erika Angle, and Wayne Matson.

Wayne R. Matson Ph.D., Chief Scientist and Co-founder.

Wayne Matson studied at the Massachusetts Institute of Technology, receiving a B.S. in Chemistry (1964) and Ph.D. (1968) in Analytical Chemistry.

From 1968-1970 at the University of Michigan as Research Associate and then Assistant Professor in the School of Public Health, he studied the sources, distribution and human effects of toxic metals. From this work it became obvious that lead in particular was a clear and present danger to children.

In 1970 he co-founded ESA, Inc. with overall responsibility for technology and programs to address this problem. He invented devices for field testing of childhood lead poisoning and nutritional deficiency, provided liaison and testimony with congressional committees for funding and led the analytical effort in the first national CDC study conclusively demonstrating the extent of elevated lead levels.

In the 1980’s he focused on the problem of chronic and neurological diseases, inventing systems and concepts for simultaneous analysis of over a thousand critical biochemicals (an area of research now called Metabolomics). On the sale of his company in 2005 he returned to Academia studying the metabolome of thousands of subjects for predictive diagnostics, individual specification of therapy and development of interventions. From this work it became obvious that there were biochemical risk factors for a number of chronic diseases and conditions that should be monitored and controlled.

He co-founded Ixcela to apply techniques in Metabolomics, Genomics and Proteomics to clinical problems of early detection of disease or disease risk, evaluation of therapies and development of risk preventive measures on a population wide basis.

He has over a hundred peer reviewed publications and US/foreign patents in the areas of instrumentation, statistical concepts, diagnostics and therapy development. His professional goal is disease prevention—one of the small classes of social problems that has technology solutions.



The Ixcela story

Ixcela was co-founded by Dr’s Erika Ebbel Angle and Wayne Matson with a group of outstanding scientists (see the biographies of our amazing co-workers). All of us had developed technologies and methods for the study of a range of diseases for diagnosis, predictive diagnostic risk factors and specification of therapy (personalized medicine).

After deep analysis of the complex biochemical profiles for over 1000 compounds in several thousand subjects, it became clear to us that the microbiome (the some 6-10,000 species in the gut – second largest organ in the body) was a critical part of the biochemical web distinguishing normal from disease subjects. Understanding these webs could also allow the prediction of therapeutic response. Additionally, the biochemistry of the microbiome had direct links to the function of other organs including the brain.

This led us beyond the ideas of diagnosis and therapy to the concept of promoting biochemical wellness (“internal fitness”) through measurement and control of the microbiome with specific, personalized intervention based on testing.


Ixcela and the “Omic web”

The basic scientific concepts behind Ixcela are:

  1. Biochemical wellness or “internal fitness” is based on optimum operation of the “Omic web” which consists of the:
    • interaction of the Genome (30,000 some genes)
    • Transcriptome and Proteome (some 100,000+ RNAs and Proteins)
    • Metabolome (some 10,000s of small signaling and process molecules)
    • Microbiome (some 6-10,000 species).
  2. That the composition of the competitive species in the Microbiome is genetically determined initially, but offers the easiest and most significant part of the Omic web for intervention.
  3. That the Omic web is “holographic” and can be well if not completely described by measuring a small subset of critical metabolites

Ixcela Technology

Ixcela’s innovative technology was developed to allow for the measurement of this critical subset of metabolites from just a small drop of blood on a piece of special filter paper. The process:

  1. Using an Ixcela Internal Fitness™ Test kit, a small drop of blood from a finger stick is placed on a filter paper pad.
  2. The kit is closed and the blood is rapidly dried to stabilize critical compounds.
  3. On receipt the exact amount of blood is determined using proprietary Ixcela technology.
  4. The 12 key metabolites of interest are then extracted from the blood on the filter paper.
  5. The metabolites are then analyzed using a liquid chromatography (LC) technique employing Electro chemical Array Detection (ECA) originally invented by Dr. Matson, which he modified for the Ixcela test for greater sensitivity (a few thousandths of a trillionth of a gram).
  6. A small amount of the extracted sample is archived for possible evaluation of any individual specific abnormalities.
  7. A report is generated from the analysis of the 12 key metabolites and evaluated against what is considered to be a normal, healthy range of levels

Ixcela’s objective

  1. To promote and facilitate internal fitness by the process of easy measurement of an individual’s biochemical state of several key metabolites
  2. To make appropriate suggestions of dietary or life-style changes
  3. To make appropriate personalized suggestions of supplements when needed
  4. Re-measure the individual’s profile periodically to monitor the beneficial effects of the changes, with the goal of improved internal fitness leading to overall better health and well-being
